摘要
针对高瓦斯矿井采区巷道特点,以晶鑫煤业武甲煤矿3#煤开采为例,观测分析了巷道收敛变形规律,并结合矿井实际设计了高预应力、强力锚杆与锚索的支护方案。工程实践证明支护方案与参数设定合理,留巷在整个服务期间变形量得到有效控制。
Accordi ng to the roadway characteristics of in mining area in high gas mine, with 3#coal in Wujia Coal Mine in Jingjin Coal Industry as an example, this paper observed and analyzed convergence and deformation law of roadway, designed the high prestressed, strong anchor with anchor cable support scheme combined with the actual mine. Engineering practice showed that support plan and parameters setting is reasonable, deformation of retained roadways had be effectively controlled during the entire service.
