矿井刀把式工作面运煤方式的改造与应用

Transformation and Application of Coal Transporting Mode in Knife-Shaped Mine Working Face

针对阳城煤电1308刀把式工作面的回采进行了可行性分析,经过初改前下运、初次改造和上行运煤改造等3个阶段的回采,相对以往打辅助工作面运输巷的回采方式,最大限度地增加了煤炭回收率,值得在开采同类型工作面时推广。

In view of feasibility analysis for the coal stoping in 1308 knife-shaped working face of Yangcheng Mine,after the three stages,such as the initial transformation,the first transformation,and the uplink coal transformation.In comparison with the previous mining auxiliary extracting method in the working face transportation lane,the recovery rate of the coal has been increased to the maximum,which is worth popularizing in the mining of the same type of working face.
