摘要:... This study was intended to measure the impact of macerals on the level of methane emission in an attempt to remove gas from coal beds. It was found that vitrinite levels in Tabas and Shahrood mines coal were 81.34% and 69.31% respectively. The methane emission rate was 0.0026...

摘要:For a gas–solid–liquid coupling model of coal seams, previous permeability models basically supposed uniaxial strains as the boundary condition for coal reservoirs without considering the deformation caused by changes in humidity. The permeability model varies under differe...

摘要:As the increase of the mining depth in China, the underground temperature, in situ stress and CH4 gas pressure also increase. Such factors have great influences on the gas drainage engineering. In this paper, the discontinuous deformation analysis is used to model the stress reli...

摘要:A thin coal seam mined as a protective coal seam above a gas outburst coal seam plays a central role in decreasing the degree of stress placed on a protected seam, thus increasing gas permeability levels and desorption capacities to dramatically eliminate gas outburst risk for th...

摘要:Abstract(#br)Chinese coal mines, which are generally of complex mining conditions, are threatened by serious coal and gas outburst and explosion accidents. Cross-measure borehole (CMB) gas drainage is one of the widely applied prevention measures, but, unfortunately, it faces ...

摘要:Abstract(#br)Modeling gas flow behaviors in coal is the basis for quantitatively predicting gas production and planning the life cycle for coalbed methane recovery. Air leakage is a tricky problem encountered in underground borehole gas drainage, which seriously affects gas extra...

摘要:Abstract(#br)Gas drainage through boreholes can effectively reduce gas disasters and significantly promote the efficient drainage and clean utilization of gas during mining activities. Gas drainage boreholes will deform and fail as the mining proceeds, but there is a lack of effe...

摘要:ABSTRACT(#br)Underground coal seam gas drainage is an effective method to lower the risk of coal and gas outburst disaster. However, it is difficult to drainage gas in the low-permeability coal seam, especially low-permeability thick coal seam with a tectonic coal sub-layer. Due ...

摘要:Abstract(#br)Coal seam gas is a kind of precious energy, but it also will be a terrible disaster in coal mining if not well controlled. Underground coal seam gas drainage is one of the most effective methods for lowering the risk of gas disaster. However, it is difficult to extra...
