针对临涣煤矿松软突出煤层工作面顺层钻孔施工遇到的问题,在改进钻进装备、钻进工艺后,钻孔进尺效果仍不理想的情况下,根据工作面煤层赋存状况,重点从瓦斯治理工程方面进行方案调整,创新性采用高位钻场内施工顶板穿层钻孔预抽、工作面面内大功率钻机施工超前卸压排放钻孔等一系列消突措施,多措并举,避开了松软突出煤层顺层钻孔施工遇到的瓶颈,消除了煤层突出危险性,保证了工作面的安全回采,取得了良好的治理效果。
Aiming at the problems encountered in the drilling of bedding coal seam in soft coal outburst in Linhuan Coal Mine, with the improvement of drilling equipment and drilling technology, the effect of drilling footage is still not ideal. According to the occurrence of coal seam in the working face, From the aspects of gas treatment project to adjust the program, the innovative use of high-level drilling site construction of the pre-drilling through the roof piercing, high-power drilling rig construction within the face of advanced pressure relief drilling and a series of measures to eliminate sudden relief measures, It avoids the bottleneck encountered in the drilling of the coal seam with the soft and prominent coal seam, eliminates the prominent danger of the coal seam and ensures the safe recovery of the working face and achieves a good governance effect.
