采场底板突水力学分析
THE MECHANICAL ANALYSIS OF WATER INRUSH FROM MINING FLOOR
【摘要】 把隔水底板作为脆性岩体,认为底板突水是由于岩体沿断裂面发生滑动造成的。考虑到矿山压力的作用,修正了莫尔—库仑破裂准则。
【Abstract】 The article takes water resisting floor as brittle rock mass,and thinks that water inrush from floor is caused by rock mass sliding along a fracture plane.Mohr Coulomb fracturing criterion is modified while under ground pressure is taken into consideration.
