不稳定厚煤层复采技术的实践

Practice on Second Mining Technology in Unstable Thick Coal Seam

煤炭资源在国民经济建设中占有重要地位,因此,保证煤炭资源的回收率显得尤为重要。有些煤矿的厚煤层第一次采过之后由于技术条件的限制或者其它因素的影响还留有很多煤没采出,浪费了很多煤炭资源。本文以教学三矿的一工作面为例,介绍复采工作面的复采工艺技术。

Coal resources play an important role in the national economy construction, so it is important to ensure the recovery of coal resources. Due to the limitations of technical condition or influence of other factors, much coal has not mined after the first mining in thick seam in some collieries, and this results in wasting a lot of coal resources. Taking one coal face of No. 3 Teaching Colliery for instance, the paper elaborates the seconding rain- ing and its technology of the coal remained in goal.
