摘要
介绍了防治特厚煤层区域洪水灌井老空水害技术现况,立足于既定的研究目标,通过理论计算防隔水煤柱宽度,应用定向钻机布置错位丛式钻孔进行探测试验,根据探测成果分析防隔水煤柱的可靠性,取得了防治特厚煤层区域洪水灌井老空水害试验的可行性,为防治煤矿灌井老空水害提供安全高效的探测方法。
This paper introduces the current situation of the technology for preventing and controlling the water hazard in the old empty space of the flood irrigation well in the extra thick coal seam area.Based on the established research goal,through theoretical calculation of the width of the waterproof coal pillar,the directional drilling machine is used to arrange the staggered cluster drilling for the detection test.According to the detection results,the reliability of the waterproof coal pillar is analyzed,and the feasibility of the test for preventing and controlling the water hazard in the old empty space of the flood irrigation well in the extra thick coal seam area is achieved.It provides a safe and efficient detection method to prevent and control the water hazard of the old empty space in the mine irrigation well.
