煤矿防治水工作中勘探方法的综合运用

煤矿矿井水灾害严重威胁着矿井的安全生产和矿工的生命安全,矿井水防治的首要条件就是查清与导水有关的裂隙发育带部位及深度等水文地质问题。本文基于对煤矿防治水勘探方法的综合运用,讨论了煤矿防治水工作中的可行性问题,并结合实际方法对在目前解决煤矿防治水工作中有一定的应用价值。

Factors Influencing the Iterative Accuracy of Ground Water Level in Forecasting the Water Burst of Deep Drawdown Mines

The purpose of this paper is to discuss the influential factors of iteration accuracy when we use iteration to determine the numerical model for predicting water yield of deep drawdown mines and calculating the groundwater level. The relationship among the calculation error of groundwater level, the pumping rate, the limit of iteration convergence error, the calculation time, and the aquifer parameters were discussed by using an ideal model. Finally, the water yield of Dianzi iron mine was predicted using the testified numerical model. It is indicated that the calculation error of groundwater level is related to the limit of iteration convergence error, the calculation time and the aquifer parameters, but not to the pumping rate and the variation of groundwater level.
