摘要
为了消除某矿15103工作面顶板多层灰岩裂隙水与3#煤层采空区积水对工作面正常安全回采的威胁,通过分析工作面顶板水水源,提出了采用钻孔探放顶板复合水的方法。应用表明:探放顶板复合水的方法成功消除了15103工作面顶板水的威胁,确保了工作面作业环境的安全。
To eliminate the threat of roof multi-storey limestone fissure water and 3^# coal goaf water of 15103 working face to the normal security mining in some mine,through analyzing the roof water sources of the working face,a method of detecting and releasing the roof compound water by drilling was proposed. Practice shows that, the method successfully eliminates the threat of roof water to 15103 working face, and ensures the normal safe working environment of the working face.
