摘　　要：工作面的回采推进会破坏采区围岩的应力平衡,是上覆岩层产生位移变形,并随着开采强度的加剧地表将产生沉陷。通过理论计算,在首阳山煤矿建立地表观测站,对3102工作面在回采期间地表岩移的变化情况进行了各类数据的实测收集。结果显示地表虽存在一定变形,但仍满足矿井后续采面布置以及地表环境的保护,为地面建筑物保护及井下生产提供可靠依据。The advance of mining in the working face will disrupt the stress balance of the surrounding rock in the mining area,causing displacement and deformation of the overlying rock layer,and with the intensification of mining intensity,surface subsidence will occur.Through theoretical calculations,a surface observation station was established in Shouyangshan coal mine to collect various data on the changes in surface rock movement during the mining period of 3102 working face.The results show that although there is some deformation on the surface,it still meets the requirements for the subsequent mining face layout and surface environment protection of the mine,providing a reliable basis for the protection of surface buildings and underground production.
