摘 要:为缓解采掘接替紧张问题、提高煤炭资源采收率,以5207运输巷为研究对象,将巷旁充填沿空留巷技术应用于运输巷中,给出充填留巷支护方案并分析留巷效果。5207运输巷充填墙体布置在采面后方采空区内,充填材料为超高水材料,同时通过锚杆、钢筋网及钢筋梯子梁提升充填墙体强度,对充填区域顶板支护、运输巷留巷段围岩补强支护设计进行了分析。现场应用后,5207运输巷巷旁充填留巷段顶底板、两帮最大变形量分别为156、115 mm,留巷段围岩保持稳定、变形量较小,巷旁充填留巷效果显著。In order to alleviate the problem of tight mining and tunnelling succession and improve the recovery rate of coal resources,the 5207 transportation roadway was taken as the research object.The roadside filling and roadway retaining technology along goaf was applied to the transportation roadway,and a filling and retention support scheme was proposed and the retention effect was analyzed.The filling wall of 5207 transportation roadway was arranged in the goaf behind the mining face,and the filling material was ultra-high water material.At the same time,the strength of the filling wall was enhanced by anchor rods,steel mesh,and steel ladder beams.An analysis was conducted on the design of roof support in the filling area and reinforcement support for the surrounding rock in the reserved section of the transportation roadway.After on-site application,the maximum deformation of the roof and floor,as well as the two sides,of the 5207 transportation roadway filling and retention section were 156 mm and 115 mm,respectively.The surrounding rock of the retention section remained stable with minimal deformation,and the filling and retention effect of the roadway was significant.
