南阳坡煤矿8800工作面过大断层开采的实践研究

Practice and Research on Large Fault Mining in the 8800 Working Face of Nanyangpo Coal Mine

本文基于南阳坡煤矿5^(#)煤层408盘区8800小煤柱工作面过5 m断层的实际难题,通过采用联合支护技术、加强回采巷道顶板管理、调整割煤工艺、预裂孔松动技术等综合技术破除瓶颈难题,实现了小煤柱工作面安全高效过断层,为其他矿井类似工程提供了借鉴经验。

Based on the practical problems of the 8800 small coal pillar working face passing 5 m fault in 408 panel area of the 5^(#)coal seam in Nanyangpo Coal Mine,the paper solves the bottleneck problems by adopting the combined support technology,strengthening the roof management of the mining roadway,adjusting the coal cutting technology and loosening the presplitting hole,and realizing the safe and efficient fault passing through the working face of the small coal pillar,which provides reference experience for other similar projects in the mine.
