粒度制御に関する研究
2012.04~2023.03, 代表者:笹岡孝司, 春日鉱山
岩戸鉱山では、地山状況の変化により起砕鉱石の細粒化あるいは大塊の発生から、起砕粒度のコントロールが課題となっている。そこで、地山条件に応じて発破規格を変更することで起砕鉱石の粒度制御ができれば、起砕鉱石の細粒化を抑制し有用鉱石の増加および細粒化鉱石の処理作業削減、あるいは大塊の発生抑制からブレーカーおよびクラッシャーの負担を軽減でき、コスト削減に大きく寄与すると考える。起砕鉱石の粒度分布に影響を及ぼすパラメータとして、最小抵抗線、孔間隔、火薬原単位(火薬量)、起爆岩盤に存在する亀裂密度、岩盤の強度を考え、粒度分布の予測の際にはこれら各パラメータが起砕物の粒度分布にどのように影響を及ぼすか定量的に評価する必要がある。そこで、当鉱山では、地山条件による発破効果の相違、各発破規格の変更に伴う発破効果への影響等について系統的に試験発破を行うとともに、通常の生産発破においてもデータを記録し、定量的な評価を行い、地山条件に基づく適切な発破規格の指針を構築することを目的とする。なお、目標とする起砕鉱石サイズは150mm~500mmとする。.
発破振動低減手法に関する研究
2012.04~2023.03, 代表者:笹岡孝司, 九州大学, 春日鉱山
春日鉱山(株)では、昨今近隣住民の方から地盤振動あるいは空気振動によるものと思われる住宅への振動被害および体感振動に関する問い合わせが寄せられており、当鉱山における発破振動の伝播状況について現状把握が急務となっている。さらに当鉱山では、今後鉱区拡大に伴う大規模な採掘ベンチの拡張作業が予定されていることから、周辺地域への発破振動の影響を最小限に抑制しながら安全かつ効率的に開発を行うためには、地質状況および地形を考慮した当鉱山およびその周辺への発破振動の伝播特性を把握するとともに、自主規制値よりも大きな発破振動が予想される場合には適切な発破振動の伝播・抑制対策を講じる必要がある。
そこで本プロジェクトでは、各種試験発破を行い、発破振動計測システムを用いて得られた振動計測結果から、当鉱山およびその周辺地域における発破振動の伝播特性を把握するともに、得られた伝播特性結果を基に数値シミュレーションを用いて適切な発破振動抑制対策を検討・提案し、その効果の検証を行うことを目的とする。.
カッタービットの摩耗特性に関する研究
2010.12~2023.03, 代表者:島田英樹, 九州大学, アルファシビルエンジニアリング
地山条件(土質条件および土質成分)からビット材質(超硬・鋼材)別の摩耗量を事前推定するための指針を得ることを本研究の目的とする。すなわち、各種土質条件および土質成分(石英の含有量・平均粒度、含水比等)における摩耗メカニズムの把握と、これら各種諸条件のビット摩耗量(材質別)に及ぼす影響について定量的評価を試みる。.

2006.10~2016.03, 代表者:松井紀久男, 九州大学, 大林道路

Takashi Sasaoka, PHANTHOUDETH Pongpanya, ULAANKHUU Batsaikhan, Hideki Shimada, TAKAMOTO Hiroshi, OYA Jiro, Study on support design for main roadway in new underground coal mine developed from open-cut highwall in Indonesia, Proceedings of 35th International Conference on Ground Control in Mining (China, 2016), 15-23, 2016.09, Indonesia is the second largest coal exporter to Japan, accounting for about 30 Mt annually. They produce over 400 Mt in 2015, over 99% of which is from open-cut mines. However, the conditions of surface mining are becoming worse year by year: the stripping ratio is increasing, approaching to the economic ratio and the infra-structure for coal transportation from inland mining areas is not prepared enough. To meet the demand for coal in Indonesia and the rest of the world, underground mines have to be developed. Under these conditions, our research program is being conducted to study the potential for underground coal mine in Indonesia through the roadway heading research program in which an underground coal mine is attempted to be developed from open pit highwall. The greatest challenge for underground coal mine development in Indonesia is safety of mine roadway in soft rock during heading, because the rock is weaker than other countries. There is a problem of possibility of heading below mobile unconsolidated soft sediment then heading move to deep area. It makes the problem of stability of support system occur due to the increase of ground pressure. The ground behavior of around roadway was measured by using Telltale, Extensometer and conver-gence measures. Moreover, the rock property tests were also conducted by using exploration drilling cores. Based on the geologi-cal data and monitoring data, a series of numerical analyses were conducted in order to discuss the appropriate support design of main roadway to 200m depth..

As, especially, the cracks in the rock mass are heavily developed at the limestone quarries in Japan, the joints and/or cracks in the rock mass have big impacts on the blasting effects such as the size of fragmented rocks. Therefore, if the joint system and/or crack density in the rock mass can be known and evaluated in quantity, the blasting operation can be done more effectively, efficiency and safety. However, the guideline for designing the appropriate blasting standard based on the rock mass condition such as mechanical properties, joint system and/or distribution of cracks, discontinuities, from the scientific point of view, has not been developed yet. Therefore, a series of blasting tests had been conducted in different mines and faces, geological conditions and blasting standards in order to know the impacts of each factor on the blasting effects. This paper summarizes the results of blasting tests and describes the impacts of rock mass conditions and blasting standard on the size of fragmented rocks..

Recently, two new underground mining trials have been conducted in East Kalimantan, Indonesia in order to investigate the possibility of the technical challenges of underground coal mines under weak geological conditions, especially the application and management of a rock bolting system. Unfortunately, one of them failed and was given up due to a fatal roof fall accident. However, in another trial, even though roof falls have occurred within the working area, the bolted roadways showed reasonable stability over time. Moreover, a comprehensive monitoring system has been installed in order to monitor the ground behaviour and its characteristics. This application of a comprehensive monitoring system has enhanced the ability to increase the level of support and to react to changing/deteriorating conditions.
This paper describes the conditions and geotechnical issues for underground mines in Indonesia and discusses the applicability of the rock bolting system under a weak strata condition in Indonesia and its technical tasks by means of site investigations and numerical analysis from the results of two underground mine trials.

However, the conditions of their surface mines are worsening each year: the stripping ratio is increasing, approaching economic ratio and the regulation of environmental protection. To meet the demand for coal, underground mines have to be developed in the near future. Under these circumstances, the development of new coal mines from open-cut highwalls are being planned in Southeast Asian countries. Moreover, some of the Southeast Asian mines have thick coal seams. However, if the conventional mining systems and designs introduced in US, Australia and European countries are applied, several geotechnical issues can be expected due to the mines’ weak geological conditions. From these backgrounds, this paper proposed a punch multi-slice mining system with stowing for thick coal seam under weak geoligical conditions and discussed its applicability and suitable design by means of numerical analysis..

However, compared with other methods, the use of explosives in blasting is limited by law as it may have a severe impact on the surrounding environment such as vibration, noise and dust. Especially, a ground vibration induced by blasting has to be paid much attention in the mining operation as it may give an obvious impact on the surrounding facilities and buildings and in many established safe level blasting criteria, the ground vibration level is characterized by using three parameters; duration, amplitude (peak particle velocity :PPV) and frequency. Current studies on the blast-induced ground vibration focus on two parameters amplitude and frequency that suggested by USBM when the concerned subject is structure, i.e.. Hence, the control of PPV and dominant frequency are very important in order to design an appropriate blasting standard and minimize its environmental impacts.

This paper discusses the propagation behavior of blast-induced ground vibration in the open pit mine and study by means of field experiments and numerical simulation. In addition, the methods for reduction of blast-induced ground vibration are also discussed by means of numerical simulation in this study.

Also, to meet requirements of haul roads in the end-wall transporting system, wide transportation benches have to be left, which makes the slope angle of the end-wall slope smaller. Consequently, a large quantity of coal has to be left under the final end-wall slope. For these remaining coal resources, they will be buried again by the inpit dumping site and are impossible to be extracted once more in future. Therefore, how to recover the remaining coal around the end-wall slope with a safe and efficient extraction system before they are buried by the inpit dump is very urgent and valuable research for open pit coal mines in China. .

method for 20-30 m thick soft coal seams at the Mae Moh coal field in Thailand. The applicability of

the longwall method for those coal seams was investigated by means of numerical method. Numerical

The surface mine pit covers is 4 km by 7 km with mining depths ranging up to 260 m. A large pit slope is formed with the progression of the mining operation. However, massive slides in the pit slope occur often due to the existence weak planes such as faults and bedding, and the weak mechanical properties of the rocks. Hence, 200 m to 300 m boundaries of rock block including coal seams are left in front of faults in order to prevent slides and maintain the stability of the pit slope. As a result, there are significant coal reserves beneath the abandoned area along the pit slope. The focus of this paper is on the applicability and design of the highwall mining for recovering much of the coal left along the pit slope..

In recent years, the distance of their construction span has been increasing and the shield tunneling system can be applied for ground that contains cobble stones and gravel soil. Therefore, the application of a shield drivage machine has become wider due to their advanced technology. However, once the conventional cutter bit hits with cobble stone and/or a boulder stone, the cutter bit fails and the cutting efficiency decreases dramatically or is completely lost. Therefore, the improvement of the impact resistance of their cutter bit is one of the major research topics for a shield tunneling system.
This paper describes the multi-layer structure bits developed in our research and discusses the impact resistance and suitable design by means of laboratory tests and numerical simulation.

coal mines, we present a residual coal extraction technology from final end-walls

with highwall mining system in China. Based on MarkBieniawski formula and

tributary area theory, the evaluation methodology of highwall mining parameters

under the thick cover was given. Furthermore, the pillar design chart in the

highwall mining system under the thick cover was also concluded. In order to

examine the rationality of the pillar design with the presented methodology,

numerical simulation was also carried out. The outcome shows that it will require

a larger pillar width with the thickening of the cover; hence, the recovery ratio will

decrease correspondingly. To improve coal recovery ratio, the backfilling

technology should be considered under the thick cover. According to twodimension

numerical simulation results, the calculated methodology for pillar

stability of highwall mining system under the thick cover presented in this article

is acceptable. It also found that keeping the pillar width-to-height ratio above 1 is

a key measure to maintain the pillar stable and integral under the thick cover.

Meanwhile, it can be concluded that the bigger safety factor is demanded for roof

of openings under much thicker cover and higher stress ratio. In other words, the

highwall mining system is feasible to extract the residual coal around end-walls in

Chinese surface coal mines. Thus, not only coal recovery ratio can be improved

but also can increase the production life of surface coal mines in China..

In the near future, the pit limit of the mine will be reached and underground mine will then be developed through the open pit in the depth of 400 - 600 m from the surface. However, due to the challenges for underground mining such as poor geological conditions, extra thickness (20 - 30 m) of coal seams, and weak mechanical properties of coal seams and the surrounding rock, the success possibility of underground mining and an applicable underground mining method is being investigated at the present. The paper discusses the applicability of multi-slice bord-and-pillar method for the soft extra thick coal seams in the Mae Moh mine by means of numerical analyses using the 3D finite difference code “FLAC3D”..

The paper discusses preliminary study on the interaction effects in underground mining of double extra-thick coal seams in Mae Moh coalfield in Thailand. The Mae Moh mine is currently operated as open pit mine by EGAT (Electricity Generating Authority of Thailand) and it is the largest open-pit lignite mine in Thailand. In the near future, the final pit limit of the mine will be reached and underground mining will be commenced from the final highwall in the depth of 400-600 m from the surface. However, due to the problems such as poor geological and geotechnical conditions, extra-thickness (20-30 m) of the coal seams and huge final pit slope, success probability for underground mine are being evaluated at the present. In the paper, it was discussed the ground response and possible interaction effects in the double extra-thick seams mining by means of numerical analyses using three dimensional finite difference code FLAC3D. .

CCC was developed from the accumulated technology of coal mining, combining the cutting technology of a shearer and the fuctions of chain conveyor. The CCC can cut harder soils and soft rocks, and vertically mixes the cut soils/rocks with cementing material selected through the discharging port installed at the bottom of the machine. In Indonesia, highwall mining trials have already been conducted in several coal mines. However, full-scale and regular operations have not been done yet due to the ground and machine control issues from their geological conditions. In order to overcome these problems, the application of CCC to highwall mining systems was proposed, and its applicability and technical issues to be solved were investigated in this research. This paper discribes the characteristics of CCC system and discusses the application of CCC to highwall mining systems. .

They produced about 250 M tons in 2010, over 99% of which being from open-cut mines. However, the conditions of surface mining are becoming worse each year: the stripping ratio is increasing, approaching the economic ratio and the infrastructure for coal transportation from inland mining areas is insufficient for such intense mining operations. To meet the demand for coal in Indonesia and the rest of the world, underground mines have to be developed. At present, there are only five small underground mines, three of which are old and the other two have only recently begun mining operations. However, severe ground control problems have been occurring regularly, roof falls in particular. Unfortunately, mining engineers and/or miners in this mine do not have a lot of experiences, expertise and know-how concerning the operations of underground coal mines.

Under these situations, since 2001, Japan has started a ‘five-year plan for coal technology transfer’ to fill Japan’s moral obligation as the largest coal importer in the world. The research team was organized and conducted on-site investigation in order to develop new underground coal mine in Indonesia.

They produced about 200 Mill. t of coal, about 75 % of which was exported in 2007. As the Indonesian government has decided on an energy policy wherein 33 % of the country’s primary energy will be met by coal by the year 2025, the domestic demand for coal has increased dramatically in recent years.
Over 99 % of coal produced in Indonesia comes from surface mines. However, surface mine conditions are worsening each year: the stripping ratio is increasing, approaching the economic ratio, and the infrastructure for coal from inland mining areas is insufficient for such intense mining operations. To meet the demand for coal in Indonesia and the rest of the world, underground mines have to be developed. However, mining engineers and/or miners do not have a lot of experiences, expertise and know-how concerning the plans and operations of collieries. Besides, they have a lot of problems and/or worse conditions such as steep coal seam, groundwater problem, stability of pit slope. Under these circumustances, the coal mine targeted in this research attempts to develop a new colliery from open-cut highwall. In order to discuss and make a suitable underground mine design such as mine layouts including panel layout and location of main entries, design and stability of pit wall, support and mining system etc., onsite investigation and numerical analysis are being conducted in this research project.

They produce over 400 Mt in 2015, over 99% of which is from open-cut mines. However, the conditions of surface mining are becoming worse year by year: the stripping ratio is increasing, approaching to the economic ratio and the infra-structure for coal transportation from inland mining areas is not prepared enough. To meet the demand for coal in Indonesia and the rest of the world, underground mines have to be developed. Under these conditions, our research program is being conducted to study the potential for underground coal mine in Indonesia through the roadway heading research program in which an underground coal mine is attempted to be developed from open pit highwall. The greatest challenge for underground coal mine development in Indonesia is safety of mine roadway in soft rock during heading, because the rock is weaker than other countries. There is a problem of possibility of heading below mobile unconsolidated soft sediment then heading move to deep area. It makes the problem of stability of support system occur due to the increase of ground pressure. The ground behavior of around roadway was measured by using Telltale, Extensometer and conver-gence measures. Moreover, the rock property tests were also conducted by using exploration drilling cores. Based on the geologi-cal data and monitoring data, a series of numerical analyses were conducted in order to discuss the appropriate support design of main roadway to 200m depth..

However, the conditions of their surface mines are worsening each year: the stripping ratio is increasing, approaching economic ratio and the regulation of environmental protection. To meet the demand for coal, underground mines have to be developed in the near future. Under these circumstances, the development of new coal mines from open-cut highwalls are being planned in Southeast Asian countries. Moreover, some of the Southeast Asian mines have thick coal seams. However, if the conventional mining systems and designs introduced in US, Australia and European countries are applied, several geotechnical issues can be expected due to the mines’ weak geological conditions. From these backgrounds, this paper proposed a punch multi-slice mining system with stowing for thick coal seam under weak geoligical conditions and discussed its applicability and suitable design by means of numerical analysis..

Also, to meet requirements of haul roads in the end-wall transporting system, wide transportation benches have to be left, which makes the slope angle of the end-wall slope smaller. Consequently, a large quantity of coal has to be left under the final end-wall slope. For these remaining coal resources, they will be buried again by the inpit dumping site and are impossible to be extracted once more in future. Therefore, how to recover the remaining coal around the end-wall slope with a safe and efficient extraction system before they are buried by the inpit dump is very urgent and valuable research for open pit coal mines in China. .

In recent years, the distance of their construction span has been increasing and the shield tunneling system can be applied for ground that contains cobble stones and gravel soil. Therefore, the application of a shield drivage machine has become wider due to their advanced technology. However, once the conventional cutter bit hits with cobble stone and/or a boulder stone, the cutter bit fails and the cutting efficiency decreases dramatically or is completely lost. Therefore, the improvement of the impact resistance of their cutter bit is one of the major research topics for a shield tunneling system.
This paper describes the multi-layer structure bits developed in our research and discusses the impact resistance and suitable design by means of laboratory tests and numerical simulation.

In recent years, the distance of each span is getting longer and longer in order to decrease the construction cost and prevent the change of bits and/or the installation of intermediate shafts.

Nay Zar LIN, Takashi SASAOKA, Hideki SHIMADA, Kikuo MATSUI, Numerical Analysis of Interaction Effects in Double Extra-thick Coal Seams Mining, International Symposium on Earth Science and Technology 2012 , 2012.09, The interaction effects in multi-seam mining depends on many factors such as local geological and geotechnical environment, mine layout, seam sequencing, and mining method employed. The paper discusses preliminary study on the interaction effects in underground mining of double extra-thick coal seams in Mae Moh coalfield in Thailand. The Mae Moh mine is currently operated as open pit mine by EGAT (Electricity Generating Authority of Thailand) and it is the largest open-pit lignite mine in Thailand. In the near future, the final pit limit of the mine will be reached and underground mining will be commenced from the final highwall in the depth of 400-600 m from the surface. However, due to the problems such as poor geological and geotechnical conditions, extra-thickness (20-30 m) of the coal seams and huge final pit slope, success probability for underground mine are being evaluated at the present. In the paper, it was discussed the ground response and possible interaction effects in the double extra-thick seams mining by means of numerical analyses using three dimensional finite difference code FLAC3D..

これまで、インドネシア坑内掘り炭鉱における坑道支保には三ツ組枠や鋼製アーチ枠が用いられていたが、1994年より豪州よりボルト支保技術を導入した。しかし、維持期間の増大に伴う経時的変形や破壊挙動がボルト支保坑道において無視できないものとなり、保坑作業を行わざるを得なくなった。現在では、ボルトの代わりに鋼製アーチ枠が再度用いられるようになっている。
本報告では、インドネシア・I炭鉱において本格的な坑内掘展開に先駆けて実施された坑内試験採掘で得られた岩盤挙動のモニタリングデータから、インドネシアの軟弱地山におけるボルト支保システムの適用性について検討した。

そこで本研究では,ビットの構造および材質,切削条件等を変化させ,これら各種要因の摩耗特性,耐衝撃性に及ぼす影響について評価を行った。

CCC was developed from the accumulated technology of coal mining, combining the cutting technology of a shearer and the fuctions of chain conveyor. The CCC can cut harder soils and soft rocks, and vertically mixes the cut soils/rocks with cementing material selected through the discharging port installed at the bottom of the machine. In Indonesia, highwall mining trials have already been conducted in several coal mines. However, full-scale and regular operations have not been done yet due to the ground and machine control issues from their geological conditions. In order to overcome these problems, the application of CCC to highwall mining systems was proposed, and its applicability and technical issues to be solved were investigated in this research. This paper discribes the characteristics of CCC system and discusses the application of CCC to highwall mining systems..

They
produced about 250 M tons in 2010, over 99% of which being from open-cut mines. However, the
conditions of surface mining are becoming worse each year: the stripping ratio is increasing, approaching
the economic ratio and the infrastructure for coal transportation from inland mining areas is insufficient
for such intense mining operations. To meet the demand for coal in Indonesia and the rest of the world,
underground mines have to be developed. At present, there are only five small underground mines, three
of which are old and the other two have only recently begun mining operations. However, severe ground
control problems have been occurring regularly, roof falls in particular. Unfortunately, mining engineers
and/or miners in this mine do not have a lot of experiences, expertise and know-how concerning the
operations of underground coal mines.
Under these situations, since 2001, Japan has started a ‘five-year plan for coal technology transfer’ to fill
Japan’s moral obligation as the largest coal importer in the world. The research team was organized and
conducted on-site investigation in order to develop new underground coal mine in Indonesia.
This paper describes the geotechnical issues for development of underground coal mine in Indonesia.

The application of rock bolting system for Indonesian underground coal mines had been attempted for a long time, but they had not been success yet. In this mining trial, even though roof falls have occurred within the working area, the bolted roadways showed a reasonable stability over time. Moreover, the comprehensive monitoring system has been installed in order to monitor the ground behaviour and its characteristics. This application of comprehensive monitoring system has enhanced the ability to increase the level of support and to react to changing/deteriorating conditions. In addition, monitoring data has allowed a quantitative assessment for future full scale mining.
This paper discusses the applicability of roof bolting system and its ground control management under weak strata condition in Indonesia by means of site investigations and numerical analysis.
