摘要
分析了工作面超前支承压力与回采巷道底鼓的关系 ,认为回采巷道底鼓是由于支承压力的影响 ,底岩层受拉应变作用离层 。
The relationship between abutment pressure distribution and floor heave of gateway is analyzed in this paper. It is considered that the condition of gateway heave is that floor strata is effected by the tensile strain come from the effect of abutment pressure. Meanwhile, the fracture rock is extruded by the horizontal stress.
