为实现永安煤矿矿井高产高效,利用其现有技术装备条件,对原有矿井工作面巷道布置进行优化设计,将采区工作面开采顺序由后退式改为往复式,双巷掘进优化为沿空留巷设计。实现了综采面连续推采,提高了设备利用率;上区段撤除切眼与下区段安装切眼布置一条线,就近搬家,回撤、安装工艺大大简化,增加了工作面生产天数。 In order to realize the high yield and high efficiency of the coal mine in Yong’an Coal Mine, the layout of the mine roadway is optimized by using the existing technology and equipment. The mining sequence of mining face is changed from reverse to reciprocating, Retaining lane design. The continuous mining and mining of fully mechanized coal mining face has been realized and the utilization rate of equipment has been increased. The removal of the upper section and the installation of a cut in the lower section of the section have been arranged. Moving, retracting and installing processes are greatly simplified and the number of production days of the working face is increased.
