普采充填工作面充填回采实践

The Practice of Stoping-and-Filling in the General Machine Mining Filling Coal Face

由于朱村煤矿井下有部分薄煤层储量,用炮采吨煤成本较高,2009年采用高档普采,并与矿业大学合作,用膏体充填处理采空区,使剩下的薄层彻底解放出来,并使矿区环境得到改善,工效提高,延长了矿井服务年限。

There are some thin seam reserves in coal mine of Zhu Village. with the high cost of blasting mining tons of coal, in 2009, high - grade general machine mining was adopted, and cooperated with the Mining University, dealing with minedout area with paste filling, so the rest of the thin seams were totally liberated out, and improve the environment, improve efficiency, and extend the service life of the coal mine.
