乌兰煤矿2#煤层上行开采可行性研究

A Feasibility Study of Ascending Mining in 2# Coal Seam of Wulan Coal Mine

神华宁夏煤业集团乌兰煤矿2裕煤层为突出煤层而长期弃采,本文就乌兰煤矿弃采的2裕煤层能否开采,通过对2裕煤层顶底板岩性分析、应用上行开采理论进行论证和实际探查,技术上可行;提出复采乌兰煤矿2裕煤层的方式,以缓解矿井接续,提高煤炭资源回收率。

2# coal seam of Wulan coal mine of Shenhua Ningxia Coal Industry Group is an outburst coal seam that has been abandoned to be mined for a long time. On whether the abandoned 2# coal seam of Wulan coal mine can be mined or not, it has been found that it is technologically feasible after analyzing roof and floor lithology together with demonstrating and actual exploration by applying ascending mining theory. The paper puts forward the mining methods of 2# coal seam of Wulan coal mine, which shall remit coal mine connection and increase recovery ratio of coal resources.
