摘要
为了提高赵庄矿低透煤层瓦斯预抽效率,决定采用水力冲孔技术对煤层进行卸压增透,在考察水力冲孔技术对矿井瓦斯治理的应用效果的同时,开展了对冲孔工艺的优化研究。试验结果显示,瓦斯抽采效率得到了有效提升。
In order to improve the efficiency of gas pre-pumping in the low permeability coal seam of Zhaozhuang Coal Mine, the hydraulic punching technology is adopted to discharge pressure and increase the permeability of the coal seam.While examining the application effect of hydraulic punching technology on gas control in coal mine, optimization research on punching technology was carried out. The test results show that the gas extraction efficiency has been effectively improved.
