摘要
公乌素矿12#煤层为薄煤层，均厚度为1．1m。该煤种为优质洗选煤种。工作面采用综合机械化采煤工艺。工作面推进速度快，每月推进100m以上；而工作面上、下顺槽均采用炮掘工艺分装分运，掘进速度慢，每月掘进100m，难以满足采煤需求，致使工作面采掘接续较困难。为了节约资源，合理开采，故工作面下顺槽采用沿空留巷技术。
It is a thin coal seam with the thickness of 1.1m in the 12# coal seam in Gongwusu coal mine, a high-quality washing type of coal,adopting comprehensive mechanized coal mining technology in the working face with advancing speed of more than 100m a month. While using gun digging process of partial shipment with slow speed of 100m a month on the crossheading of the working plane, it is difficult to meet the demand of coal mining to toughen the difficulty of working face mining succeeded. In order to save resources and mining reasonably, the gob-side entry retaining technology is used under the working face of the mining crossheading.
