摘要
为了解决超薄基岩浅埋煤层过沟谷开采问题,以神府矿区杨伙盘煤矿30108、30110工作面过沟谷开采方案设计为例,论述过沟谷开采的必要性和可行性,结合周边类似矿井的开采情况,提出了三个可行的过沟谷开采方案。并从安全、技术、经济方面进行比选,得出"沟内覆土+井下铺设柔性网+均压通风"是符合杨伙盘煤矿的有效方案,为同类矿井开采提供了新的解决途径。
In order to solve the problem in ultra-thin bedrock shallow seam mining crossing gully,we take the design of gully-crossing mining scheme for 30108 and 30110 working face of Yanghuopan Coal Mine in Shenfu Mining Area as an example,discussed the necessity and feasibility of gully-crossing mining,combined with investigations of similar coal mines around,put forward three feasible gully-crossing mining schemes,which were thoroughly compared from the security,technology and economy view. The result shows that,the 'in-gully soil covering + underground flexible mesh + even-pressure ventilation'scheme is effective for Yanghuopan Coal Mine,which provides a new solution for the similar mines.
