| 摘 要： | 某井田周围的水源丰富，导致煤矿开采过程中出现了严重的涌水问题，对煤矿生产安全构成了一定程度的威胁。在对井田特征及主要水体进行简要介绍的基础上，分析了井田附近的水文地质特征。基于钻孔实验研究了11100掘进工作面围岩的水文地质情况，基于实验结果对工作面不同区域进行分区。利用综合探测、疏水降压和注浆加固技术制定了煤层底板承压水防治措施方案。通过实践应用发现取得了很好的效果，疏放水量达到了2万m3，工作面底板的钻孔承压值由最大时的0.76 MPa降到0。

| Abstract: | The abundant water sources around a mine field have led to serious water inflow problems during coal mining,posing a certain degree of threat to the safety of coal mine production.Based on a brief introduction to the characteristics of the well field and main water bodies,the hydrogeological features near the well field were analyzed.Based on the drilling experiment,the hydrogeological conditions of the surrounding rock of the 11100 working face were studied,and different areas of the working face were divided based on the experimental results.Using comprehensive detection,hydrophobic pressure reduction and grouting reinforcement technology,a plan for preventing and controlling the confined water in the coal seam floor was formulated.Through practical application,it was found that good results had been achieved,the drainage water volume had reached 20 000 m3,and the borehole pressure value of the bottom plate of the working face had been reduced from the maximum 0.76 MPa to 0. |
