高压水射流割缝卸压技术在复杂地质条件矿井中的应用

Application of high pressure water jet slotting pressure relief technology in mines with complex geological conditions

为综合治理复杂地质条件下矿井灾害治理,特别是针对水文地质构造复杂,瓦斯、冲击地压严重的矿井,采取高压水射流割缝卸压施工技术,不仅能有效进行瓦斯抽采,同时使煤体在一定范围内得到充分卸压,实现了防冲卸压和瓦斯快速高效抽采目的。研究为复杂地质条件下瓦斯和冲击地压灾害的协同防治提供了一种新的思路。

In order to comprehensively control mine disasters under complex geological conditions,especially for mines with complex hydrogeological structure and serious gas and rock burst,the high pressure water jet slotting pressure relief construction technology is adopted,which can not only effectively carry out gas drainage,but also fully relieve the pressure of the coal within a certain range,so as to realize the purpose of impact prevention and pressure relief and rapid and efficient gas drainage.The research provides a new idea for the coordinated prevention and control of gas and rockburst disasters under complex geological conditions.
