厚煤层孤岛工作面收尾技术研究

Study on Closing Technology of Isolated Island Working Face in Thick Coal Seam

以高河矿E1303厚煤层孤岛工作面为研究对象,通过加强停采时煤帮支护强度、保证顺槽超前区域安全、做好收尾期间机头、机尾三角区域的管理,同时,对停采线侧煤帮进行注浆加固,增强巷道顶板支护强度,有效缩短了放顶煤工作面收尾时间,保障收尾期间撤架工作安全迅速,推动了矿井安全高效生产。

Taking the isolated island face of E1303 thick coal seam in Gaohe Mine as the research object, by strengthening the strength of coal support, ensuring the advance area safety of the CIS trough, making the head and tail triangle area management during the end of the end, grouting reinforcement to the side coal side of the stop production line, strengthening the strength of roadway roof support, effectively shortening the top coal caving coal. The closing time of the working face ensures the safety and speedy work of the withdrawal during the ending period, and promotes the safe and efficient production of the mine.
