摘要
近距离煤层采空区下工作面巷道顶板破碎,稳定性差,支护比较困难。本文以杜儿坪矿69301工作面轨道巷实际条件为背景,利用理论计算的方法,合理计算巷道支护参数,确定支护方案,为类似条件下巷道支护提供经验。
It is more difficult to support the roof of the working face in the close distance coal seam, because of the broken roof and poor stability in the roadway. Based on a discussion of the actual condition of 69301 face track lane in Duerping Mine, the paper determines the support scheme, by means of theoretical calculation and reasonable calculation of roadway support parameter, providing useful experience for mine roadway support under similar conditions.
