摘　　要：针对煤矿开采导致工作面覆岩及地表地质变化问题,为解决此问题以同煤某矿工作面为例,在分析煤层、地质以及顶底板条件的基础上,采用模拟试验方式对工作面覆岩变化情况进行分析,采用全站测试仪对工作面地表的动态和稳态参数进行测量,为后续煤矿开采的地质治理提供依据。In order to solve the problem of geological changes of working face overburden and surface caused by coal mining,taking a working face of Tongmei coal mine as an example,based on the analysis of coal seam,geology and roof and floor conditions,the simulation test method is used to analyze the changes of working face overburden,and the total station tester is used to measure the dynamic and steady parameters of working face surface,It provides the basis for the geological treatment of subsequent coal mining.
