王庄矿矸石混凝土间隔充填连续采煤工艺研究

为了解决煤矿资源紧缺问题,提高矿井产量、延长矿井服务年限,针对王庄煤矿的煤层赋存条件,提出了一种利用矸石混凝土间隔充填,连续采煤机短臂机械化采煤工艺,并对采煤工作面设备进行了选型,实践证明该采煤方法可用于开采＂三下＂压煤及不适合布置长壁工作面的边角煤。

Study the mining technology of waste concrete interval filling and continuous mining in Wangzhuang coal mine

In order to solve the problem of shortage of coal resources, improve mine production, extend the mine service life. According to the storage situation of the coal seam in Wangzhuang coal mine, proposed a mining method of waste concrete interval filling and shortwall face mechanical coal mining using of continuous miner, and select the device model used to coal face, the method is applicable to mining the coal seam there are buildings above it, or the area of coal is so small that we can not layout the longwall system.
