摘　　要：文章以九龙地区某矿床为研究对象,分析了矿区水文地质条件。结果表明:矿区为一中间高三面低的地垒型构造格架,有利于地浅表大气降水的排泄;矿区水文地质单元较为封闭,为一以静储量为主的水文地质单元;矿床充水因素受大气降水以及外界水文地质单元补给较为,矿床充水主要与内部孤立的含水层密切相关;矿区深部奥陶系灰岩含水层水位变化滞后于降雨集中时段2月~3月,总体上对资源开采有利。The article analyzes the hydrogeological conditions of a mining area with a deposit in Jiulong area as the research object.The results show that the mining area is a low ground-based structure frame in the middle of the middle and three sides,which is beneficial to the excretion of atmospheric precipitation on the surface of the surface,the hydrogeological unit of the mining area is more closed,is a hydrogeological unit mainly based on static reserves,and the water-filling factor of the deposit is more supplemented by atmospheric precipitation and the external hydrogeological unit.The filling of mineral deposits is mainly closely related to the internal isolated aquifers,and the change of water level of the deep Otao gray rock aquifer in the mining area lags behind the rainfall concentration period from February to March,which is beneficial to the exploitation of resources in general.
