一侧临空巷道掘进矿压显现规律及顶板控制

摘要

根据回采工作面周围支承压力、采动引起的岩层压力分布规律理论，松动圈理论及锚杆锚索联合支护理论，为矿井第一个一侧临空巷道在相邻综放工作面回采期间快速掘进、提供顶板控制依据，选择合理支护参数、优化支护设计，跟踪整个施工过程、分析矿压显现规律，为矿井后期临空巷道顶板控制奠定坚实基础。%According to the distribution rules of abutment pressure around working face and strata pressure caused by mining, as well as broken zone and bolt-anchor supporting theory, the study provides evidences for rapid driving and roof control of the first roadway along gob in the adjacent fully-mechanized mining face. Reasonable supporting parameters and an optimized design are selected. By following the whole construction process and analyzing the strata behavior, the study is also a firm basis for the late roof control in the roadways along gob.
