Support Design and Application of Working Face Gateway about Close Distance Coal Seam in Dongqu Coal Mine

近距离煤层巷道受采动影响,存在压力大、巷道维护困难、维修率高等问题。本文通过分析已有巷道支护设计中存在的不足,提出了全新的支护方案,并从成本及支护效果两方面进行对比,分析了新支护方案的可行性,可为同类巷道的支护提供借鉴。

There are some problems with roadway of close distance coal seam of which is affected by mining, such as high pressure, difficulty of roadway safeguard, high maintenance rate and so on. The insufficient which exists in current roadway support design is analyzed, so the new support programs are put forward, and the new programs are compared in both cost and support effect. The feasibility of new support program is analyzed, it can provide reference for roadway support of same type.
