工作面底板突水预测

Prediction of Water Inrush from Floor of Working Face

底板突水不仅造成严重的经济损失还要浪费很多的地下水资源,所以对水害的预测显得尤其重要,是煤矿安全生产的重要因素。结合工作面的实际条件,首先使用经验公式来计算出底板最大破坏深度,然后以此结果为基础采用突水系数法、临界水压力法对底板突水危险性进行分析,最后对工作面底板突水进行预测。

Water inrush from floor not only causes serious economic losses but also wastes a lot of groundwater resources, so the prediction of water damage is especially important, and it is an important factor for the safety production of the coal mine.According to the actual conditions of the working face,the maximum failure depth of the floor is calculated using the empirical formula, and then the water inrush risk of the floor is analyzed by the water inrush coefficient method and the critical water pressure method. Finally, the water inrush from the floor of the working face is predicted.
