Groundwater outburst has an impartible relationship with geological structures such as water-conducting faults, which are widely distributed in north China. In order to study the seepage property and mechanism of water outburst from the faults above a confined aquifer in the coal mining, the...

In order to study the relationship between the deformation mechanism and permeability on brittle rock, the curves of stress–strain and permeability–strain of brittle rock were analyzed, the results indicated that the permeability of brittle rock increased rapidly at the critical failure...
