豫西雷门沟钼矿水文地质条件分析及涌水量预测

豫西熊耳山雷门沟钼矿床位于东秦岭多金属成矿带东段,是已探明的超大型斑岩型钼矿,前人研究程度高、地质成果丰硕,但对矿床开采技术条件方面研究较少。本次通过地质调查工程、水文地质试验等方法,从水文地质角度,对雷门沟钼矿床水文地质条件进行研究,填补了该方面的空白,丰富了研究成果；采用水文地质比拟法预测未来矿坑最大排水量2613 m³/d,经实践检验结果较为可靠；总结的采坑排水量预测方法、含水层特点、矿床充水因素以及防治水措施,以期对该区域水文地质工作具有参考价值。

Analysis of hydrogeological conditions and prediction of water inflow in Leimengou molybdenum mine,western Henan Province

Located in the eastern part of the East Qinling polymetallic metallogenic belt, the Xiongershan Leimengou molybdenum deposit in western Henan Province is a super-large porphyry molybdenum deposit with high degree of previous research and fruitful geological achievements, but there is little research on the mining technical conditions of the deposit. Through the methods of geological survey engineering and hydrogeological test, this paper studies the hydrogeological conditions of Leimengou molybdenum deposit from the point of view of hydrogeology, which fills the gap in this aspect and enriches the research achievement. the hydrogeological analogy method is used to predict the maximum displacement of 2613 m ~ 3 percussion d in the future, and the result is more reliable. The summarized prediction method of pit displacement, characteristics of aquifer, water filling factors of deposit and water prevention measures are of great reference value to the hydrogeological work in this area.
