摘　　要：补连塔煤矿22501综采工作面宽度300 m,推进长度562.3 m,回采面积16.8万m2。煤厚1.5~1.8 m,煤层平均厚度1.6 m,倾角为1°~3°,地层总的趋势是以极缓的坡度向北西倾斜的单斜构造,倾角1°~3°,断层不发育,后生裂隙发育。根据四壁顺槽揭露情况,工作面无断层、冲刷等构造。对工作面初次来压及周期来压,特殊地质条件下来压情况进行了详细介绍,对类似综采工作面的回采具有指导意义。The width of 22501 fully mechanized face in Bulianta Coal Mine is 300 m,the thrust length is 562.3 m,the mining area is 168000 m2.The thickness of coal seam is 1.5-1.8 m,the average thickness of coal seam is 1.6 m,and the dip angle is 1°-3°.According to the exposed situation of the four-wall trough,the working face has no faults,scour and other structures.This paper introduces in detail the first weighting and periodic weighting of the working face and the weighting under special geological conditions,which is of guiding significance for the future mining of similar fully mechanized coal face.
