摘要
在采掘作业中,煌斑岩侵入区域内,煤层受煌斑岩不规则的穿插侵入,破坏严重,局部煤层挤压变薄,煤层变质为高灰煤。并且煌斑岩硬度高,严重影响正常开采。本文旨在研究工作面过煌斑岩的开采技术,为作业队组在煤层煌斑岩区域开采时提供一定的借鉴经验和实践指导。
In the mining operations, in the lamprophyre invasion region, because of the lamprophyre irregularly invasion, coal seam suffered serious destruction, thinned in local extrusion area, and formed the high ash coal, and lamprophyre hardness is high, which seriously affect the normal production. The aim of this paper is to research mining technology of working face mining through lamprophyre, and provide some reference and practical guidance for team working group in coal seam lamprophyres.
