| 摘 要： | 为了准确掌握工作面的充水条件及制定有针对性的顶板水害防治措施，在对顶板含水层进行划分并获取其水文地质参数的基础上，采用关键层理论、数值模拟和相似材料模拟对工作面导水裂隙带高度进行了预测，从而实现了工作面充水因素的精细探查；利用顶板含水层静储量叠加动态补给量的方法对工作面的涌水量进行精细化预测，结合工作面顶板含水层疏放水量观测值对疏放水效果进行定量化评价，评价结果表明工作面已经达到了安全回采的水文地质条件。通过实例分析，对工作面水文地质条件进行精细化探查，采用“动—静”水量的工作面涌水量预测方法，结合顶板含水层疏放水效果定量化判别方法，可以保障工作面的安全开采。

| Abstract: | In order to accurately grasp the water filling conditions of the working face and formulate the targeted prevention and control measures of roof water disaster，based on the division of the roof aquifer and the acquisition of its hydrogeological parameters，the key layer theory，numerical simulation and similar material simulation were used to predict the height of the water conducting fracture zone of the working face，so as to realize the fine exploration of the water filling factors of working face；and the roof aquifer was used to predict the height of the water conducting fracture zone.The method of superposition of static reserves and dynamic replenishment of water layer were used to fine predict the water inflow of working face.Combined with the observation value of the water drainage of the roof aquifer of working face，the quantitative evaluation of the water drainage effect was carried out.The evaluation results showed that the working face has reached the hydrogeological conditions of safe mining.Through the case analysis，the hydrogeological conditions of the working face were fine explored.The prediction method of water inflow of the working face with "dynamic static" water volume and the quantitative discrimination method of the drainage effect of the roof aquifer can ensure the safe mining of the working face. |
