摘　　要：针对高压单轨防水闸门硐室不适宜双轨运输巷的情况,以裴沟矿-300水平轨道巷防水闸门硐室为研究对象,采用理论计算、数值模拟及现场试验相结合的方法,选取防水闸门硐室主要参数,模拟出-300水平轨道巷防水闸门硐室受采动影响时应力场、位移场及破坏区特征。提出双轨防水闸门硐室双壳支护技术,并进行现场工业性试验。采用KJ327-F型顶板离层监测系统对双壳支护条件下防水闸门硐室顶板活动规律监测结果表明,受32071工作面采动影响,-300轨道大巷防水闸门以帮部变形为主,防水闸门采用双壳支护有效控制了围岩强烈变形。According to the situation that the chamber with high-pressure monorail water-proof gate no longer fits the double track haulage roadway, taking the chamber with waterproof gate in --300 level orbital alleys of Peigou mine as the study object, the paper chooses the main parameters of the waterproof gate chamber, and simulates the stress field, displacement field and failure zone features of waterproof gate chamber under the mining influence with the methods of theoretical calculation, numerical simulation and field test. And it puts forward the double shell supporting technology and conducts the field industrial test. The KJ327-F type roof separation monitoring system is used to monitor the moving regularity of the roof of waterproof gate chamber under the double shell supporting condition, and the results show that under the mining influence of 32071 working face, waterproof gate in --300 track roadway failures mainly in sides, and the double shell supporting effectively prevents the severe deformation of the surrounding rock.
