摘要
为了掌握综采放顶煤条件下的地表沉陷规律,通过设置地表移动观测站,总结了孔庄煤矿综采放顶煤条件下的地表移动变形规律及地表下沉特征,并结合相邻采区分层综采工作面的地表实测数据,对比分析了综放开采条件下与分层综采条件下的的地表沉陷规律。
Through the analysis of surface subsidence data from surface mobile measurement instrument , the special regularity of surface movement is investigated. Both the slicing mining and caving mining was considered, and the regularity of surface moment and character of surface subsidence is given.
