薄煤层综采工作面托伪顶开采技术

Mining Technology with Boosting False Roof at Fully Mechanized Coal Face in Thin Coal Seam

鸡西矿业集团东山煤矿现有地质储量2.0亿t,可采储量1.0亿t,其中薄煤层储量占总储量的67%,进行薄煤层的安全高效开采势在必行。为此,在6B薄煤层且托伪顶开采上进行了生产实践,总结了一套薄煤层开采和托伪顶开采的顶板管理方法,填补了托复合软顶回采的空白,为今后实现薄煤层安全高效生产打下良好的基础。

In Dongshan Coal Mine in Jixi Mining Industry Group,there are the existing geological reserves of 200 million tons and recoverable reserves 100 million tons,in which thin coal seam reserves account for 67% of total reserves,the thin coal seam mining with safety and efficiency is imperative.To this end,the production practice with boosting false roof mining in 6B coal seam was in progress.A set of roof management method of the thin coal seam mining and boosting false roof mining was summed up.The blank of booing compound soft roof mining was filled up. A good foundation was laid in order to realize the safe and efficient mining in future.
