Research
Research Interests
  • Study on estimation of slaking behavior of argillaceous rock
    keyword : Slake durability, Testing method
    2006.07~2018.03.
  • Research on the Ground Control Problems in Mining
    keyword : Mine, Ground Control, Support System, Slope Stability, Stability of Openings
    2006.07~2018.03Title: Study on Ground Control in Mining Abstract: Underground and open-pit mining involve a number of complex issues for the mining industry ranging from ensuring the safety of miners and the public to maximizing the recovery of ore reserves. Particular challenges are presented by mining under conditions of highly stressed or weak rock masses, mining at greater depth, and mining under permafrost and frontier conditions..
  • Study on control blasting -Environment Friendly-
    keyword : Blasting, Control of Particle Size, Control of Blast Vibration, Noise, Environment
    2006.07~2018.03Title: Study on control blasting Abstract: Blasting technique has been widely used in mining and civil engineering fields as one of the efficient methods. In the mining industry, especially surface mine, blasting is the primary mechanism for ore/rock breakage and represents a significant portion of the total mining costs. The size of fragmentation also has a big impact on the performance and productivity of loading, hauling, crushing and grinding procedures. Hence, it can be said that the controlling/optimizing fragmentation size, in other words, the optimizing blasting design at each site, is the important key for improving the productivity and reducing the total costs in the mining operation. On the other hand, from the safety and/or environment points of view, blasting design also has to be reconsidered in order to reduce vibration to the acceptable levels surrounding area. From these points of view, the guideline for optimizing blasting design based on the geological conditions has to be developed. But, in order to develop this guideline, it has be to evaluate the effects of geological conditions (structural properties and mechanical properties) and the each items of blasting standard on the fragmentation size and blast vibration in quantity. Hence, field experiments were conducted in order to collect data under different mine/geological conditions/blasting designs..
  • Study on the abrasive behavior of cutter bit
    keyword : Abrasiveness, cutter bit
    2010.08~2018.03.
  • Study on control of acid mine drainage at opuncut coal mine
    keyword : Acid Mine Drainage, Surface Mine
    2007.04~2018.03Study on control of acid mine drainage at opuncut coal mine.
  • Study on the utilization of flyash
    keyword : Flyash, Utilization
    2006.07~2018.03Title : Study on the utilization of flyash Abstract : A large amount of flyash from the coal combustion is produced. About 55% of flyash in Japan is now utilized and the remains are dumped at disposal sites; however, the life of these sites is limited. Therefore, in this study, an effort was made to apply flyash for civil engineering field as flyash cement and/or for environmental issues (e.g. a barrier materials for unclear waste disposal)..
  • Study on fluid behavior of grouting materials into rock/soil
    keyword : Grouting Material, Rock Mass, Soil, Seepage Behavior
    2006.07~2018.03Title : Study on fluid behavior of grouting materials into rock/soil Abstract : The injection process into the rock voids is classified into three large processes. There are a transportation process of cement particles, a clogging process in the rock voids and a hardening process. In the analysis, the clogging process and the transportation process were analyzed. As to the analysis of the clogging process, the material transport equation considering the filtration theory was introduced and used. As to the analysis of the transportation process, the equation of the plug flow that was related to Bingham fluid instead of Darcy’s law was expanded and used. From the results of these analyses, the existence of grout concentration corresponding to the purpose was suggested..
  • Study on effect of chemical grout injection on stability of soil and environment
    keyword : Chemical Grouting, Improvement of Soil Characteristics, Unsolid Grouting Material
    2006.07~2018.03Title : Study on effect of chemical grout injection on stability of soil and environment Abstract : In order to maintain a permanent stability of the surrounding soil, chemical grouting material is injected. However, the behavior of the chemical grouting material in the surrounding soil around the tunnel has not yet been clearly understood. Hence, in an effort to identify the performance of the chemical grouting material in the surrounding soil, it can be applied to the seepage and dispersion behavior of the chemical grouting material by using the Eulerian-Lagrangian analysis..
  • Study on application of rock cutting machine for construction of undetground pipeline by pipe jacking
    keyword : pipeline, rock cutting
    2006.07~2018.03.
