摘要
钻孔封孔深度是影响瓦斯抽采效果的关键因素之一。根据王坡煤矿现场实际情况,通过数值模拟和现场试验研究制定出了相应瓦斯抽采钻孔封孔深度优化技术方案。该方案提高了抽采钻孔的封孔质量和经济效益,对提升矿井瓦斯治理水平具有重要意义。
Sealing depth of drilled hole is one of the key factors affecting gas extraction effect. According to the actual situation of Wangpo Coal Mine, this paper formulated the corresponding technical scheme for optimizing the sealing depth of gas drainage drilling holes through numerical simulation and field test research. The scheme improves the sealing quality and economic benefits of the extraction borehole and is of great significance for improving the level of mine gas control.
