基于二级判别法的煤层底板突水预测研究

Prediction of Water Inrush from Coal Seam Floor Based on Two Level Discriminant Method

为准确实现底板突水的预测预报,分析归纳淄博矿区历年突水实例的数据资料和淄博矿区底板突水与水压及隔水层厚度关系,在此基础上提出运用二级判别法构建底板突水判别函数,建立煤层底板突水的判别方法。通过该判别体系对淄博矿区历年突水工作面进行底板突水预测,预测结果历史概括率高,符合工程实际。

To achieve accurate prediction of the water inrush, analyzing Zibo mining historical data and examples of water inrush from Zibo mine water inrush and the water pressure and the thickness of water resisting layer, used two stage method to construct water inrush discriminant function, establish the discriminant method of coal floor water inrush. According to the prediction of water irtrush from the floor of Zibo mining area over the years, the result of the system is high, and it is in accordance with the engineering practice.
