采空区上覆薄煤层回采实践

Practice of Mining in Thin Coal Seam on Mine Goaf

介绍了中盛煤矿在资源已近枯竭的情况下,对10#主采煤层采空区上覆9#薄煤层的开采过程中,采取的工作面布置方式、掘进、回采技术措施,以及为预防在采掘期间采空区底板裂隙漏风采取的安全技术措施,实现了安全回采。试验性开采的成功,有效地回收了采空区上覆的薄煤层,为蹬空储量的开采积累了经验,延长了矿井服务年限,实现了矿井的可持续发展。

Introduces in the arrangement of working face, the technical measure of tunneling and stoping in the process of stoping for 9^# coal seam which is located on the coal goaf. It＇s to adopt a safely practice which makes coal mining safely for the air leak of floor in the process of coal mining. New techniques makes it successful to recover usable thin coal seam on the coal goaf. Accumulates the experience, extends the service life of the mine and realizes sustainable development.
