摘　　要：贵州响水煤矿3#煤层12309回采工作面停采后,离工作面较近地表未发现裂隙,远离工作面地表反而出现明显裂隙,针对这一现象,运用UDEC软件对12309采面进行了仿真数值模拟实验,通过模拟实验得到:采深172 m的开切眼前后出现两组裂隙,裂隙呈"V"字形;停采线处,水平离层裂隙和竖向破断裂隙贯通至地表冲沟;变坡面裂隙发育,稳定性差,会发生滑坡。When the 12309 working face the 3# coal seam in Xiangshui Mine of Guizhou stopped to mine,the place near the working face did not come into being the fracture,the surface which was far away from working face appeaed much fracture.In reaction to the phenomenon,using UDEC software went to numerically simulate to The 12309 working face.The results show that open-off cut in 172 m deep discovered two groups of fracture liked “V”.On the terminus line,the level of delamination fracture and vertical fracture fissure ran through the surface gully.The fracture developed in variable slope,it was lack of stability and would lead to landslides.
