| 摘 要： | 摘 要] 基于区域水文地质条件研究,结合新安县郁山铝土矿床的地质结构特征,详细论述了郁
山铝土矿床的水文地质特征。矿区内主要含水层为碳酸盐岩类裂隙岩溶水含水层和碎屑岩类裂隙水含
水层,中等-弱富水性;主要隔水层为石炭系本溪组顶部泥岩、石炭-二叠系太原组泥岩隔水层( 顶板隔
水层)和石炭系本溪组中、下部泥岩隔水层( 底板隔水层)。大气降水和地下径流是矿区地下水的主要
补给来源,人工开采和泉是矿区地下水的主要排泄方式。断裂带具储水与导水性质,通常构成联通各含
水层的垂向通道。地下水是矿床充水的主要水源,地表水及大气降水为矿床充水的影响因素。充水通
道以渗入性通道为主,局部可以形成溃入性充水通道。所以,新安县郁山铝土矿为顶、底板直接充水的
水文地质条件中等复杂的以溶蚀裂隙为主的岩溶充水矿床。 |

| Abstract: | Based on the research on regional hydrogeological conditions,combining with geological structure characteristics of the Yushan bauxite deposit,this paper elaborates the hydrogeological characteristics of the Yushan bauxite deposit in Xin’an county,Henan Province.The aquifer in this deposit is dominated by fissure karst water in carbonate rocks and fissure water in clastic rocks,and the water abundance is medium to weak.The mudstone on the top of the Carboniferous Benxi formation mudstone,Taiyuan formation Mudstone of permo-Carboniferous(water-resistion roof layer),and the mudstone at the lower part of Carboniferous Benxi Formation(water-resistion bottom layer) are the main impervious beds.The main recharge sources of groundwater include meteoric rainfall and underground runoff,while its major discharge forms include artificial water-taking and spring discharge.Fault zones usually serve as vertical channels which link different aquifers because of their water storage and conductivity.Underground water is the main source,and surface water and meteoric rainfall are the influencing factors of deposit water filling.Water-filled channels are the primary penetrated courses,and gushing channels can be formed locally.Therefore,the Yushan bauxite in Xin’an county is a karst water-filled deposit where the roof and bottom are filled with water directly,with an intermediately complex hydrogeological condition and dominant karst water filling. |
