摘要
文章研究了定向钻探技术在掘进巷道地质防治水中的应用,分析了工作面顶板的含水层特性,其中Ⅲ含水层被确定为直接的水源补给层,Ⅱ含水层充当间接的水源补给源头。研究结果还揭示了钻孔进尺与水量密切相关;结合富水性指数计算,绘制等值线图,评估了含水层富水性分布特点。应用结果表明,定向钻探技术可有效减少巷道涌水量,提高采矿作业的安全性和稳定性。
This paper studies the application of direction-al drilling technology in geological water prevention and control in tunneling roadways,and analyzes the character-istics of aquifers in the roof of the working face.Among them,aquifer Ⅲ is determined as direct water supply layer,and aquifer Ⅱ acts as indirect water supply source.The research results also reveal that the drilling footage is closely related to the water quantity;combined with the calculation of aquifer productivity index,the contour map is drawn to evaluate the distribution characteristics of aquifer water abundance.The application results show that the direc-tional drilling technology can effectively reduce the water inflow in roadways and improve the safety and stability of mining operation.
