大孔径“以孔代巷”高位定向裂隙带抽采钻孔瓦斯治理技术研究

Gas Control Technology of Large-diameter"Hole Instead of Roadway"High-position Directional Fracture Zone Drainage

通过实验分析120 mm孔径高位裂隙长钻孔瓦斯治理技术和203 mm大孔径“以孔代巷”瓦斯治理技术的抽采数据,找出高位裂隙带长钻孔的最佳层位,通过数据对比,探索替代高抽巷抽采的可行性,保证矿井集约高效生产。

Based on the experimental analysis of the gas drainage data of 120 mm bore-hole and 203 mm large bore-hole gas treatment technology,the best position of long bore-hole in high-level fracture zone is found out,to explore the feasibility of replacing high extraction roadway and ensure the intensive and efficient production of mine.
