矿井涌水量预测方法探讨

Exploration on the Prediction Methods of Coal Mining Water Inflow

为研究矿井涌水量,在对比分析预计与实际矿井涌水量的基础上,指出80%以上的矿山的预计涌水量与实际相差超过50%,并分析了影响预计结果与实际不符的主控因素。在分析矿井涌水量现行主要预测方法的特点和优、劣势的基础上,给出不同阶段适用的预测方法,并结合工程实例进行分析。此外,对如何准确预测钻孔涌水量与大井法预测中存在的问题及解决方案进行了探讨。最后,给出了对矿井涌水量预计的几点认识。

The comparative analysis of expected and actual mine water inflow showed that more than 80% coal mining water inflow predictions were not correct compared with the actural water inflow, the error ratio over 50% , and the main controlling factors that affected the prediction result were analyzed. Based on analyzing the characteristics, advantages and disadvantages of the current main prediction methods, the applicable prediction methods at different stages were providedand analyzed with the practical engineering examples. In addition, how to accurately predict the existence of prediction of water inflow and the problems existing in the drilling well and their solutions were discussed. Finally, some opinions on the prediction of mine water inflow were given as the suggestion.
