The purpose of this article is to present the hydrographic and hydrochemical properties of the waters of old adits, which drained excavations after exploitation of iron ores. For this research, both the natural springs and control object have been identified. These are located in the Cieszyn Foothills. It has been shown that adit water has a higher average electrolytic conductivity (> 600 µS/cm) than natural spring water (<300 µS/cm). The increase in conductivity is undoubtedly influenced by the air supply to the excavations, which accelerates the rock weathering process. However, the increase in water mineralisation has no effect on the hydrochemical type of water. Adit waters and spring waters represent the same bicarbonate calcium (HCO₃⁻ - Ca²⁺) hydrochemical type. Adit waters show a small variation in water temperature in the annual cycle (C_v < 8%) compared to a natural spring (C_v -18%). Changes in the water temperature in the adits and the spring show high synchronism (r> 0.7).

本文的目的是介绍在开采铁矿石后排空挖掘工作的旧坑水的水文和水化学性质。对于这项研究，已经确定了天然弹簧和控制对象。这些位于Cieszyn山麓地区。已经显示，adit水的平均电解电导率（> 600 µS / cm）比天然泉水（<300 µS / cm）高。毫无疑问，电导率的增加受开挖空气的影响，从而加速了岩石的风化过程。但是，水矿化的增加对水的水化学类型没有影响。硐水域和泉水代表相同的碳酸氢钙（HCO ₃ ^- - CA ²⁺）水化学类型。与天然泉水（C _v -18％）相比，平顶水在年循环中的水温变化很小（C _v <8 ％）。犬牙和春季水温的变化显示出高度的同步性（r> 0.7）。
