随着矿井开采强度加大,采空区周边采掘活动增多,由顶板来压、矿震引起密闭压裂或巷道裂隙沟通,形成较为畅通的采空区漏风环境.通过对两种充填堵漏材料性能分析,提出了密闭间充填 LFM 轻型材料和停采线外钻孔压注 BX 高水材料的封堵措施,成功消除了隐患.

@@@@As the mining intensity and goaf side activities increased, confined fracturing or roadway fissures connection caused by roof pres-sure or earthquake have formed relatively unimpeded air leakage environment along goaf. Through analysis of two kinds filling & plugging ma-terial properties, the sealing and plugging measures of filling LFM light material at confined area and drilling and filling BX high water materi-al outside stopping lines have successfully eliminated hidden dangers.
