针对某矿井深部倾斜煤层综采中存在的主要问题,进行巷道布置合理优化,引入错层位巷道布置采全厚采煤法.进一步发展完善错层位巷道布置体系,根据实际情况,将进风巷完全布置在顶板稳定的岩层中,将回风巷布置成半煤岩巷,并结合具体问题进行技术分析,运用有限差分软件FLAC3D进行了模拟验证.结果表明:这种布置方式能保证煤矿的安全生产,提高采出率,降低巷道维护成本,并有效防治冲击地压等一系列问题.
In view of the main problems existing in the fully mechanized mining of the deep inclined coal seam in a certain mine, the layout of the roadway is reasonably optimized and the full-thickness coal mining method is introduced in the staggered-level roadway layout. The alley is completely arranged in a stable rock roof and the return air lane is arranged in a semi-coal rock roadway, and the technical analysis is carried out according to specific problems, and the simulation is carried out by using the finite difference software FLAC3D.The results show that the arrangement can ensure the coal mine Safe production, improve recovery rate, reduce roadway maintenance costs, and effectively prevent a series of problems such as rock burst.
