The balance method of determining the share of Kryvyi Rig Basin enterprises by the accumulated volume of mine water in the storage pond was considered. The balance method of participation of mining enterprises by the shares of mineral substances was formalized. An integrated approach of the control of water removal into the storage pond when using the linear convolution of two balance equations by both the share of water volumes and the mineralization rate in the water discharges of enterprises was developed. It takes into account the choice of equity participation in mine water removal by economic and environmental criteria. The algorithm of equity participation of mining enterprises of Kryvyi Rih Basin on the principles of equality of two criteria was substantiated. The calculations of the share of discharge water accumulation in the storage pond of the Svistunov gully were carried out. The estimated price for water removal of one cubic meter of water into the storage pond by two criteria was considered. The estimation criteria are the volumes of pumped water and mineralization rate. Graphical dependences of the estimated price on the ratio of discharges concentration of different enterprises to the mixture concentration were built. Different estimation coefficients were used: paid water removal by water volumes; assessment of water removal only by mineralization rate; equal approach by the volumes (50%) and mineralization rate (50%). The calculations showed the efficiency of the algorithm, the applicability of its use by enterprises for integrated control of mine water removal by the criteria of volume and mineralization rate. The proposed balance method can be easily generalized when using other indicators of water quality (chlorides, sulfates, etc.), which are considered to be the most relevant for determining the equity participation of enterprises. In the future it is necessary to develop a theory of paid water use and water removal in conditions of unsatisfactory water quality, taking into account the integrated approach by different indicators that means multi-criteria assessment of water removal and accumulation of mine water.
