摘要
提出了承压水上采煤的裂隙介质固流耦合数学模型及其数值模拟解法，介绍了西峪煤矿承压水上采煤问题进行的数值试验方法及结论，研究了推进速度、煤柱宽度与水压、煤柱应力、断层渗透系数、断层变形之间的相互关系．
The solid-liquid coupling mathematic model of fracture media and numeric simulation solution are put forward when mining over confined aquifer, and the numerical solution experimentation and conclusion for mining over confined aquifer in Xiyu Coal Mine is detailed introduced, the relationship between advanced speed,coal protect pillar width and water pressure, protect pillar stress, permeability coefficient of fault, and fault deformation are studied.
