摘　　要：老里湾银矿床位于豫西崤山断隆区,是河南省探获的首个大型独立斑岩型银矿床,前期研究程度高,但是针对矿床开采技术条件方面研究较少。通过水文地质调查、地下水动态长期观测、水文地质试验等方法,从水文地质角度,对老里湾银矿床水文地质条件进行研究,丰富了研究成果。采用水动力学法结合相邻矿区排水经验,预测矿坑最大排水量1222.26 m^(3)/d,与矿坑排水量对比基本符合实际情况;对本地区开展同类型矿床水文地质研究工作,具有重要的参考意义。Laoliwan silver deposit,located at the fault uplift area of Xiaoshan in the west of Henan Province,is the first large independent porphyry silver deposit discovered in Henan Province,with a high degree of previous research,but there is little research on the mining technical conditions of the deposit.Through the methods of hydrogeological survey,long view of groundwater dynamics and hydrogeological test,this paper studies the hydrogeological conditions of Laoliwan silver deposit from the point of view of hydrogeology,which enriches the research results.By using the hydrodynamic method combined with the drainage experience of the adjacent mining area,the maximum drainage volume of 1222.26 m^(3)/d is estimated to calculate,which is basically in line with the actual situation.It has an important reference significance to carry out the same type of hydrogeological work in this region.
