锡林郭勒盟农乃庙井田充水因素分析及涌水量预测

Analysis on Water Filling Factors and Predication of Water Yield in Nongnaimiao Well

摘要:

简要介绍了农乃庙井田水文地质概况，井田的充水因素分析，包括含水层、隔水层的分布及断层导水性的分析，并结合相关实际情况利用矿井涌水量预测计算方法对第一水平先期开采地段的矿井涌水量进行预测。此次仅适用于矿井开采初期，后期应根据实际矿井涌水量的变化情况进行合理修改。下一步应探测研究上部间接含水层对矿井开采及坑道系统充水作用的影响，确保安全生产。

Abstract:

In this paper, basic situation of hydrological conditions of Nongnaimiao well have been briefly introduced. Water filling factors analysis include the distribution of aquifer and aquiclude, and fault conductivity analysis. Combining with actual situation, by using mine water inflow forecast calculation method, water inflow predication of the first mining mines at the first level has been carried out.This applies only to the early mine mining, the late should according to the actual change of mine water inflow is reasonable modifications. The next step is to detect the upper indirect aquifer water filling effects on the mine mining and tunnel system, the influence of ensure safety in production.
