摘　　要：为了更好地服务矿井生产,掌握西部地区浅埋煤层开采后地表变形特点,以隆德矿2-2煤层开采为工程背景,采用现场实测法对2-2煤201采面回采后的地表变形参数进行监测,并具体确定了岩移参数,给出了2-2煤层开采后地表变形特点。研究成果可为矿井护巷煤柱留设以及“三下”煤层开采等工作提供一定指导。In order to better serve the mine production and grasp the characteristics of surface deformation after mining of shallow coal seam in Western China,taking the mining of the 2-2 coal seam in Longde Mine as the engineering background,the field measurement method is used to monitor the surface deformation parameters after mining of 201 coal face of the 2-2 coal seam,and the specific rock movement parameters are determined,and the characteristics of surface deformation after mining of the 2-2 coal seam are given.The research results can provide certain guidance for the work of retaining roadway pillars and"three lower"coal seam mining.
