俯斜开采工作面综合防治水技术分析

Analysis of Integrated Water Prevention and Control Technology in Inclined Mining Face

俯斜开采工作面防治水是煤矿安全开采的难题之一。以实际俯斜开采工作面为例,分析了工作面含水层和排水系统情况,运用钻探、注浆等综合防治水措施查明水文地质情况,并采取针对性措施降低了工作面涌水量;同时,采用有效导流上覆含水层涌水的方法,大幅度降低了工作面排水压力,保障了工作面安全回采。

The prevention and control of water in the inclined mining face is one of the difficulties in safe mining of coal mines. Taking the actual inclined mining face as an example, this paper analyzed the aquifer and drainage system of the working face. The comprehensive water control measures such as drilling and grouting were used to ascertain the hydrogeological conditions, and targeted measures were taken to reduce the amount of water in the working face. At the same time, the method of effectively guiding the water burst in the overburden aquifer was adopted, which greatly reduced the drainage pressure of the working face and ensured the safe mining of the working face.
