摘要:On the background of the specific geological and mining conditions of a coal mine,the experimental study was made on slip pattern of two sides of fault and phenomenon of water inrush affected by the working face under the solid-liquid coupling mode by similar material simulation experiment. The research indicates that the fault zone has a "barrier", the higher concentration of stress will be formed in the roof and baseplate of the coal pillar; interface of hanging wall either vertical or horizontal displacement are more displacement than interface of footwall. Whether the hanging wall of the fault or fault footwall, vertical displacement of the interface is larger than horizontal displacement; The larger permeability of bottom strata rock, risk of water inrush is greater; under the same width of coal pillar, the greater water pressure of aquifer, the greater risk of water inrush.
