综采工作面过空巷技术实践

Practice on the Technology of Passing Abandoned Roadways in Fully Mechanized Mining Face

对巷道现状进行了研究,由于矿井煤层及地质构造的影响,回采工作面中部有一条垂直正副两巷的巷道(二切巷),重点分析了沙坪煤业过二切巷需要采取的措施、存在的问题及结果。得出采取适当措施,有望在确保安全前提下,增加煤炭资源的回收,获得了巨大经济效益。

The present situation of roadways is studied. Due to the impact of coal seams and geological structure of the mine, there is a roadway （two-cutting roadway） perpendicular to the main and auxiliary roadways in central stope. The measures need to be taken, problems and results in passing two-cutting roadway of Shaping Coal Industry. are focused on. It is expected to increase the recycling of coal resources in the premise of ensuring safety by taking appropriate measures, by which huge economic benefits can be gotten.
