The object of research is the process scheme with adjustable mine water disposal mode of «Lubelska» № 1-2 mine via the channel «Butynsky» in the river Rata (Ukraine), and – the impact on the most vulnerable components of the environment – surface water and groundwater of Lviv-Volyn coal basin. In connection with the change in the projected method of shaft sinking it is necessary to review and adjust the system of mine water disposal during the building period. For this work it is analyzed and summarized hydrogeochemical data obtained in the course of monitoring observations in the course of 3 years in the control supervisory sections of «Butynsky» channel and the river Rata. As a result, the technical possibilities and environmental friendliness for adjustment of mine water disposal scheme in the second stage of shaft sinking (during building) are shown. The method of flow diagram adjustment of mine water disposal is chosen. It can be done in two modes, on the basis of the prediction of quantity and quality composition of the mine water. The first mode – discharge in accordance with the predicted value of the mine water inflow: minimum periods of water inflow – 30-40 m3/h with a salinity of 20 g/dm3 and periods of high water inflow – 80-90 m3/h with a salinity of 10 g/dm3. The second mode – the accumulation of mine water in the settling ponds, mixing them with drainage water formed as a result of drainage of the industrial site of «Lubelska» № 1-2 mine and with rain water, then – averaging and discharge in a volume up to 90-100 m3/h with salinity up to 5-7 g/dm3. This disposal scheme will improve the environmental safety of mine water disposal into surface water bodies, regulate the conditions of mine water discharge, as well as their quality within the allowable concentrations and, thus, minimize the impact on the hydrochemical regime of surface water of Butynsky channel and the river Rata.
