摘要
为进一步提升矿井防治水的效果,以某煤矿2号煤层顶板的防治水为例,将定向钻孔技术应用其中,并根据该工作面地质、水文以及顶底板情况完成钻孔位置及相关技术参数的设计,为钻孔的实施配置有效的装备和实施工艺,并对最终定向钻孔在2号煤层工作面的防治水效果进行验证.
In order to further improve the effect of mine water prevention and control,taking the prevention and control water of coal seam No.2 as an example,the directional drilling technology is applied,and the drilling position and related technical param eters are designed according to the geological,hydrological and roof and floor conditions of the working face.The water control effect of the final directional drilling in No.2 coal seam face is verified.
