摘　　要：冀中能源峰峰集团辛安矿属于衰老矿井,找煤增量、延长矿井寿命是急需解决的问题,本文在分析112811工作面开采现状对南副井、风井等影响的基础上,采用地表移动概率积分法,计算出适用于辛安矿井筒的允许变形指标,井筒的下移量小于等于200 mm,竖向压缩变形值小于等于1.50 mm/m。研究分析了综放工作面在整个回采过程中,对岩体和地面的影响,对指导矿井安全生产具有实际意义。Xin’an Mine of Jizhong Energy Fengfeng Group is an aging mine,and it is an urgent problem to find the increment of coal and prolong the life of the mine.Based on the analysis of the influence of the mining status of No.112811 Face on the south auxiliary shaft and air shaft,the allowable deformation index suitable for Xin’an mine shaft was calculated by using the probability integral method of surface movement.The down displacement of the shaft was less than or equal to 200 mm,and the vertical compression deformation was less than or equal to 1.50 mm/m.The study analyzed the influence of fully mechanized caving face on rock mass and ground during the whole mining process,which had practical significance for guiding the safe production of mines.
