摘　　要：为了得到斜沟煤矿综放开采条件下采场裂隙带发育高度及演化特征,根据斜沟矿的地质资料,通过数值计算、RFPA模拟及现场验证,研究了煤层开采后覆岩在采动影响下纵横向裂隙的分布、发育及相互贯通规律,得到工作面开采后覆岩破断与垮落规律,划分"三带"的分布区域,验证了RFPA模拟方法是采动覆岩"两带"高度研究的有效手段。In order to obtain the development height and characteristics of the stope fissure zone under the condition of fully mechanized caving mining in Xiegou Coal Mine,according to the geological data of Xiegou Mine,the distribution,development and interconnection of vertical and horizontal fissures of overburden rock under the influence of mining are studied through numerical calculation,RFPA simulation and field verification.The law of overburden rock breakage and collapse after mining is obtained,and the distribution of"three zones"is divided.It is verified that RFPA simulation method is effective in studying the"two zones"height of mining overburden.
