摘要
为进一步提升煤矿综采工作面开采煤炭的回收率,降低煤炭资源浪费的同时,减少煤炭开采成本,在对9110综采工作面地质条件分析的基础上,提出采用沿空留巷工艺对其进行开闸;并根据工作面实际情况重点完成了沿空留巷巷旁和巷内支护方案设计,为实现高效率开采奠定基础。
In order to further improve the recovery rate of coal mined in the comprehensive mining face,reduce the waste of coal resources at the same time,reduce the cost of coal mining,on the basis of the analysis of the geological conditions of the 9110 comprehensive mining face,it is proposed to adopt the process of leaving the roadway along the air to open the gate;and according to the actual conditions of the face,it focuses on the completion of the design of the support scheme of the roadway along the air to leave the roadway next to the roadway and the roadway,in order to realize the foundation of high-efficiency mining.
