摘要
为获取七采区3下煤层综合机械化开采地表移动规律,在南屯煤矿73下21东西两工作面上方分别设立了地表移动观测站,通过对实测资料的分析与研究,得到了南屯煤矿该区域综采条件下的地表移动变形规律与岩移角值参数。针对两工作面地表下沉数据分别求取了相应的地表移动概率积分法模型参数,并综合2组反演结果给出1套完整的地表沉陷预计参数。
To get the law of surface movement of 3under coal by mechanized caving mining in seven mining area, Nantun coal mine established surface ground movement observation stations at the top of working face 73 under 21(west) and 73 under 21, through analysis and research of the measured data,the ground movement rules and different kinds of angle parameters are obtained under the condition of mechanized mining, the appropriate parameters of surface movement based on probability integration method is obtained from subsidence data of the two working face.
