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。
In order to accurately forecast the water inrush from the floor, the data of the water inrush from the Zibo mining area in past years and the relationship between water inrush and water pressure and the thickness of water-barrier in Zibo mining area are analyzed. Based on this, Water discriminant function, the establishment of coal floor water inrush discrimination method. The water inrush forecast of the water inrush working face of Zibo mining area in past years is predicted by this discriminant system. The forecast result has a high historical generalization rate, which is consistent with the actual project.
