特厚煤层放顶煤工作面高效收尾技术实践

Technical Practice on Efficient Ending in Extra-thick Coal Seam with Caving Face

以斜沟煤矿23103特厚放顶煤工作面为研究对象,通过停采线的确定、整体提溜、调斜、工作面铺网、回撤通道支护等工序,确定了放顶煤工作面高效收尾合理的技术参数,降低了巷道支护难度,缩短了收尾时间,保证了矿井安全高效生产。

Taking 23103 extra-thick caving coal face in Xiegou coal mine as the research object, the reasonable technical parameters in caving work was determined by the determination of stop-mining line, overall lifting of scraper conveyor, adjusting the head and tail of the scraper conveyor, lay out net in work face, retrieving of roadway support The practice reduced the difficulty of roadway support and shortened the close-up time, the safe and efficient produc- tion of the mine ensured
