Purpose. To estimate the parameters of calcium leaching from fractured carbonate rocks under various geochemical conditions of man-caused karst,and to evaluate relevant changes of flow properties.

Methodology includes the experiments of dissolution of calcium carbonate samples in reproduced solutions of different ion composition and mineralization as well as analytical assessment of flow parameters changes of fractured carbonate rocks.

Findings. Laboratory studies and analytical evaluations have been carried out. The experiments of dissolution of limestone massive samples using solutions of different compositions and ionic intensity allowed quantifying the kinetics of calcium leaching from the rock. As a result of qualitative assessment of saturating the model mixtures with calcium carbonate a high activity of solutions against cavernous limestone has been established. Analytical studies have determined the ranges of parameters that quantify leaching in carbonate rocks.

Originality. First time the experiments have been conducted to study the mutual reaction between massive samples of Neogen limestone and solutions reproducing man-changed ground waters. The rate of carbonates dissolution in solutions of different content as well as the factors influencing on changes of rocks solubility have been identified and leaching kinetics has been evaluated.

Practical value. The results obtained allow proper evaluating the seepage-induced deformations of carbonate rocks under the impacts of mine waters of different chemical composition. It makes possible to enhance the trustworthiness of salt transport prediction in limestone in the zones affected by tailing facilities.
