摘    要:将近水平煤层开采的上覆岩层运动与地表沉陷作为一个整体系统进行研究,论述了采场上覆岩层的运动规律和裂隙拱的形成及发展变化过程。并结合地表沉陷的GPS观测,确定了针对具体地质条件的地表移动变形边界角、移动角,找到了井下工作面推进位置与地表下沉速度之间的关系。

关 键 词:矿山压力  岩层运动  地表沉陷

Abstract:We can look the stratum movement and subsidence as a whole system to study. The common nature of stratum movement and the development procedure of crack arch are described. Meanwhile, based on the ground observation by the global positioning system (GPS), the boundary angle and the motion angle, which aim at special geologic conditions, are determined. The relation between the position of underground working face and ground subsidence velocity are found.
Keywords:rock pressure in mine  stratum movement  ground subsidence
