| 为确保带压开采工作面实现安全回采,满足《煤矿防治水规定》要求,以邢台某矿5519工作面为例,介绍其范围内含水层及隔水层分布情况,并对该工作面回采前的顶、底板充水因素进行了分析,结果表明煤层顶板的野青灰岩含水层、5#煤顶板砂岩含水层及煤层底板的砂岩层和伏青灰岩含水层为直接充水水源,需重点防范.最后利用突水系数法对工作面回采安全性进行评价.评价结果显示工作面基本满足安全开采要求,通过采取一系列防探水措施后,工作面可以安全回采.该评价结果对于类似条件下工作面的安全回采具有重要的参考意义. |

| In order to ensure the mining working face under pressure to realize safety mining and meet the requirements of the prevention and control of coal mine water regulation, this paper focused on the analysis of aquifer and water-resisting layer and the filling water factors of 5519 working face of a Xingtai Coal Mine. Results show that the Yeqing limestone aquifer, the sandstone aquifer of 5# coal roof and floor and Fuqing limestone aquifer for direct water filling water needs to focus on prevention, and the water inrush coefficient method is applied to the evaluation on the safety of 5519 working face. Results also show that the working face meets the requirements of safety in mining. Ground water prevention measures are implemented to ensure to realize safety mining of 5519 working face. The evaluation result has important referential significance for the similar working face. |
