凉水井煤矿综采工作面风桥优化设计研究

Research on the optimization design of air crossing for fully mechanized mining face in Liangshuijing coal mine

通过优化42205综采工作面风桥设计,将422盘区42205工作面的3条回采巷道变为422盘区隧道北区42201-42204工作面的开拓大巷,既减少了巷道施工工程量,又能满足各工作面回采期间的运输和通风需要,取得了较好的经济效益。

By optimizing the design of air crossing in No. 42205 fully mechanized mining face, three mining roadways of No. 42205 working face in No. 422 panel are changed into the development roadways of No. 42201- No. 42204 working faces in north of No.422 panel,which not only reduces the amount of roadway construction, but also meets the transportation and ventilation requirements of each working face during the mining period, and achieves better economic benefits.
