钻探技术在煤矿水害防治工作中的应用

Application of Drilling Technology in Coal Mine Water Hazard Control

摘要:

钻探作为煤矿水害防治工作一种重要的技术手段，得到了广泛的应用。煤矿大口径排水井钻进技术、底板多分支水平井地面定向钻进及注浆加固改造技术、井下定向探（疏）放水钻进技术、注浆封堵突水通道钻探技术和矿井突水灾害快速钻进救援技术等煤矿防治水钻探技术，在煤矿水害防治工作中得到了广泛应用，取得了良好效果。加强防治水钻探配套设备的研发和相关钻探工艺技术研究，将有力促进煤矿水害防治工作的发展。

Abstract:

As an important technical approach to control coal mine water hazard, drilling technology has been widely used. The application of coal mine water hazard control technologies, such as large diameter drainage well drilling, ground floor multi-branch horizontal wells by surface directional drilling and grouting reinforcement and reconstruction, underground directional drainage drilling, grouting to seal water inrush passage drilling and rapid rescue drilling of mine inrush disaster, has received good effects. Further development of drilling equipments for water control and the research on related drilling technologies should promote coal mine water hazard control.
