摘要
根据鸡西矿业集团平岗煤矿东一采区14#层煤层赋存条件,结合锚杆、锚索支护机理进行理论分析,合理选择14#层煤巷道复合顶板支护方式和支护参数;分析了复合顶板巷道帮、顶封闭式支护技术效果和经济效益。
According to the occurrence condintions in No.14 coal seam east No.1 mining area in Pinggang Coal Mine in Jixi Mining Industry Group, the mechanism of bolt and cable support is analyzed.The support way and parameters of compound roof in the coal roadway in No.14 coal seam are reasonably chosen.The technical effect and economic efficiency of closed support at side and roof in compound roof roadways are analyzed.
