Slotting effect on pressure relief during gas drainage of low permeability coal
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 relief effect of drillin...
