摘要
本文首先针对李粮店煤矿开拓巷道围岩变形现状分析该处地应力规律,最后根据本矿大采深软岩的特点提出采用锚架注联合支护技术,为深部巷道合理支护和煤层安全高效开采做了一次较好的尝试。
This paper aimed at the grain shop lee coal mine development present situation analysis of the surrounding rock of roadway deformation law of ground stress, finally according to the characteristics of the mine mining of deep soft rock anchor frame joint injection supporting technology is presented in this paper, reasonable for the deep roadway supporting and safe and efficient mining of coal seam made a good try.
