基于水文地质条件分析的工作面涌水量预测研究

Study on Prediction of Water Inflow of Working Face Based on Analysis of Hydrogeological Conditions

为探究杨村煤矿南翼下组煤拟开采的10603工作面涌水量,系统分析了影响该工作面涌水量的地质及水文地质条件,提出影响该工作面涌水量的主要充水含水层为十下灰岩和十三-十四灰。在此基础上,采用水文地质比拟法和大井法分别对该工作面涌水量进行了预测,最终确定了该工作面正常和最大涌水量取值。研究结果对该工作面排水系统设计和水害防治具有重要的参考价值。

In order to explore the water inflow of the 10603 working face to be mined in the lower group of the south wing of Yangcun Coal Mine,the geological and hydrogeological conditions affecting the water inflow of the working face are systematically analyzed,and it is proposed that the main water filling aquifers affecting the water inflow of the working face are tendown limestone and thirteen-fourteen limestone.On this basis,hydrogeological analogy method and large well method are used to predict the water inflow of the working face,and finally determine the values of normal and maximum water inflow of the working face.The research results have important reference value for the drainage system design and water disaster prevention of the working face.
