摘　　要：分析了皖北矿区煤层底板岩溶水常规离子水化学特征,并采用常规离子水质浓度梯度和Ca^(2+)水化学平衡两种分析方法,对皖北矿区岩溶系统水循环特征进行了研究,指出岩溶水系统在矿区内TDS和△[Ca^(2+)]值由北向南呈逐渐增高的趋势,北部有一个低TDS与△[Ca^(2+)]值带,南部有两高TDS与高△[Ca^(2+)]值带。In this paper, the authors have analyzed the hydrochemical characteristics in karst water of the coal seam floor in the mining area of North Anhui and studies the circulation characteristics of the Karst water by means of the concentration grads of water quality and hydrochemical equation of Ca2 + . It is pointed out that TDS and △[ Ca2+ ] in the Karst system of the mining district have a increasing trend from north to south and there is a low value zone of TDS and △[ Ca+] in the north and two high value zones in the south.
