摘要
为掌握上屯留煤矿上覆岩层的发育特征,以该矿S2106工作面为研究对象,采用UDEC数值模拟软件建立了数值模型,对其上覆岩层的移动规律进行了研究,并得出以下结论:工作面推进45 m时,冒落带高度发育到了31 m,且基本上不再向上发育;当工作面推进60 m时,裂隙带高度为61 m,基本上也不再随着工作面的推进向上发育。
In order to understand the overlying strata development characteristics in Shangtunliu coal mine,taking the S2106 working face as an example,the numerical model is established by dopting UDEC numerical simulation software so as to analyze the displacement laws of overlying strata. The results show that when the working face advance 45 m,the height of the caving zones development to 31 m,and no longer upward development basically; when the working face advance 60 m,the height of the fissure zone is 61 m,and it is not upward development with the advances of working face basically.
