use as a simulated underground gasifier, which comprised coal blocks excavated from the coal seam. This study
reports the process and results of three independently designed experiments using coaxial-hole and linking-hole
UCG models: (a) a coaxial model using a coaxial pipeline as a gasification channel, (b) a coaxial model using the
coaxial pipeline combined with a bottom cross-hole, and (c) a linking-hole model using a horizontal V-shaped
cross-hole. In the present work, the fracturing activities and cavity growth inside the reactor were monitored
with acoustic emission (AE) technologies. During the process, the temperature profiles, gas production rate, and
gas content were measured successively. The results show that AE activities monitored during UCG process are
significantly affected by operational variables such as feed gas rate, feed gas content, and linking-hole types.
Moreover, the amount of coal consumed during UCG process were estimated using both of the stoichiometric
approach and balance computation of carbon (C) based on the product gas contents. A maximum error of less
than 10% was observed in these methods, in which the gas leakage was also considered. This demonstrates that
the estimated results using the proposed stoichiometric approach could be useful for evaluating energy recovery
during UCG..

1. Akihiro HAMANAKA, Hiroto YAMASAKI, Takashi SASAOKA, Hideki SHIMADA, Shinji MATSUMOTO, Application of Fly Ash to Acidic Soil to Improve Plant Growth in Disturbed Land of Open-cut Mining, 18th Symposium on Environmental Issues and Waste Management in Energy and Mineral Production, 2018.11, The amount of fly ash disposed as industrial wastes is increasing with increasing coal demands all over the world. Although fly ash is generally disposed by landfill, the demand of effective utilization of them is increasing because of the limitation of the disposal site. 80 % of coal ash is utilized such as a material for cements though less of them are disposed by landfill. Considering the preparation of landfill area and environmental issues, it is very meaningful to discuss the utilization of fly ash except a cement usage. Most of coal is mined by open-pit mining method in Indonesia. A broad post-mining area is built after the mining operation. The broad area has to be revegetated in terms of environmental conservation. However, soil acidification caused by mixing acid sulfate rocks or soils mined in the operation influences the revegetation. As the plant growth is inhibited under the acidic conditions, the utilization of fly ash which has higher neutralizing capacity due to its alkalinity is expected in order to improve the conditions of seedbed in the revegetation area. In this paper, the utilization of fly ash for preparation of seedbed in disturbed land in Indonesian open cut coal mine is discussed by means of laboratory pot trials by using simulated acidic soil with a mixture of pyrite, fly ash which has higher alkalinity, and Acacia mangium which is a typical species planted for fast growing tree in Indonesia. The results suggested that the appropriate mixture of fly ash to neutralize the acidic soil can be improved the plant growth under the acidic condition..
