摘　　要：以唐安煤矿三盘区3307工作面需将轨道巷保留,作为临近工作面的皮带巷为工程背景,介绍了沿空留巷切顶卸压技术;阐述了锚杆(索)三大支护理论,提出在3307工作面沿空留巷采用“锚杆+锚索+金属网+柔模混凝土+锚栓”的综合支护技术,监测了沿空留巷的围岩位移量,结果表明,围岩位移量在可控范围内。In order to keep the track Lane of 3307 working face in Sanpan District of Tang'an coal mine as the belt roadway near the working face as the engineering background.This paper introduces the roof cutting and pressure relief technology of gob-side entry retaining,expounds the three supporting theories of bolt and cable,puts forward the comprehensive support technology of"bolt"+"anchor cable"+"metal mesh"+"flexible-formwork concrete"+"anchor bolt"in gob side entry retaining in 3307 working face,monitors the surrounding rock displacement of gob side entry retaining,and the results show that the displacement of surrounding rock is within the controllable range.

关 键 词：沿空留巷 切顶卸压 综合支护 位移量
