高压磨料水力割缝技术在高突煤层的应用

摘要

High-pressure abrasive hydraulic cutting Seam technology Can efficiently reduce the coalseam elastic energy and high-pressure internal energy of the gas in the aera with serious outburst, it can reduce the risk of gas outburst.Meanwhile it can raise the Coalseam gas drainage efficiency,shorten the time of gas drainage,Increase the speed of drivage.%低抽巷高压磨料水力割缝技术能有效降低高突危险区域的煤体弹性潜能和高压瓦斯内能，降低瓦斯突出危险性；能有效提高煤层瓦斯抽放效果、缩短瓦斯抽放时间、提高巷道掘进速度。
