摘要
受地表建筑物以及煤层位置厚度影响,条带开采工作面选择较多。某矿区采储量位于村庄下,工作面走向正好垂直穿过村庄规划的房屋,为解决矿区内村庄下煤柱的开采难题和安全生产,在矿区2206条采工作面布设了地表岩移观测站,观测分析地表变化规律。分析出了相邻监测点之间的沉降差值、曲率、变形值和开采系数等特征参数,研究了该矿区的地表下沉机理,为该区域的地表土地开采沉陷与塌陷赔偿、房屋变形改造以及综合利用等方面提供了技术支持。
Due to the influence of the surface buildings and the thickness of the coal seam position,there are many mining faces.In order to solve the mining problem and safety production of coal pillar under the village in the mining area,the surface rock movement observation station is set up in 2206 mining faces to observe and analyze the law of surface change.The characteristic parameters of settlement difference,curvature,deformation value and mining coefficient between adjacent monitoring points are analyzed,and the mechanism of surface subsidence in the mining area is studied,which provides technical support for the mining subsidence and compensation of collapse of surface land in the area,housing deformation transformation and comprehensive utilization.
