基于定向钻进的高承压底板水害防治研究

Research on Water Inrush Prevention of High Pressure Floor Mine Based on Directional Drilling

利用定向钻进技术进行底板注浆改造。并与相邻工作面普通注浆效果进行对比。表明基于定向钻进技术的底板注浆改造效果明显优于普通注浆改造技术。对矿区高承压底板岩溶水的水害防治具有一定的借鉴意义。

Using directional drilling technology to transform the ordinary grouting effect of adjacent working face. The results grouting based on directional drilling technology is obviously There is important significance to the prevention of mine water water. floor grouting. And compared with the show that the grouting effect of floor better than that of ordinary grouting. inrush in high-pressured floor of karst water.
