摘　　要：为有效提升1302运输顺槽区域瓦斯抽采效率,通过理论分析水力冲孔卸压增透原理及施工工艺,结合1302运输顺槽的具体地质条件,进行水力冲孔卸压增透试验分析,具体设计水力冲孔各项参数,在水力冲孔方案实施后,瓦斯抽采期间进行瓦斯抽采量和造穴区域剩余瓦斯含量的分析。结果表明:水力造穴方案实施后,造穴区域瓦斯抽采浓度和纯量均较高,抽采效率高,水力冲孔卸压增透效果显著。In order to effectively improve the efficiency of gas drainage in the 1302 transportation channel,the principle and construction technology of hydraulic punching,pressure relief and penetration enhancement are analyzed theoretically,combined with the specific geological conditions of the 1302 transportation channel,and the hydraulic punching pressure relief and penetration enhancement test analysis is carried out.Design the various parameters of hydraulic punching.After the hydraulic punching plan is implemented,the gas drainage volume and the remaining gas content in the cave-making area will be analyzed during the gas drainage.The results show that after the hydraulic cavitation plan is implemented,the gas drainage concentration and scalar in the cavitation area are both high,the drainage efficiency is high,and the hydraulic punching pressure relief and permeability enhancement effect is significant.
