摘要
在厚煤层开采过程中有大量的巷道开挖工程,为确保在采矿区中快速有效地开采,顶板和底板基于参数测试,采用孔切顶留巷支护技术,并在原巷道基础上使用顶板锚索和木垛,并布置金属网防止矸石进入到运输巷。采用钻孔切顶留巷支护技术可以保证巷道稳定,满足了开采中巷道使用的需要。
There are a large number of roadway excavation projects in the process of thick coal seam mining.In order to ensure rapid and effective mining in the mining area,the roof and floor are based on parameter test,and the supporting technology of hole cutting top and retaining roadway is adopted.On the basis of the original roadway,roof anchor cables and wooden cribs are used,and metal mesh is arranged to prevent waste rock from entering the transportation roadway.The support technology of cutting top and retaining roadway by drilling can ensure the stability of roadway and meet the needs of roadway use in mining.
