Massive deformation often occurs when deep coalmine roadways pass through a fault zone due to the poor integrity of rock mass and high tectonic stress. To study characteristics surrounding in coalmine, roadway passing FD1041 China’s Gugui coalfield was investigated this research. The geo-stress were analyzed based on Mohr failure theory. Furthermore, three-dimensional model for experimental bui...

Elastic modulus (E) is a key parameter in predicting the ability of material to withstand pressure and plays critical role design rock engineering projects. E has broad applications stability structures mining, petroleum, geotechnical engineering, etc. can be determined directly by conducting laboratory tests, which are time consuming, require high-quality core samples costly modern instruments...

Adsorbed gas is one of the crucial occurrences in shale reservoirs; thus, it great significance to ascertain adsorption capacity and characteristics CH4. In this investigation, Taiyuan–Shanxi Formations’ coal-measure reservoir Carboniferous–Permian era Hedong Coalfield was treated as research target. Our results exhibit that samples were characterized by a high total organic carbon (TOC) over h...
