There are given the basic results of research of mechanism of salinization of open pit waters at Mikashevichy building stone deposit, disposed into the river system. There is offered a complex of nature-protection measures, directed on stabilization of process of mineralization of open pit waters, as the design depth of deposit mastering is reached. For the purpose of realization of complex of measures (particularly, construction of ground water cutoff), there was developed the program of pre-project operations, directed on detail research of basic sources of formation of mineralization of open pit waters and specification of construction of water supply crushing zone (where the mineralized waters are delivered into the open pit). This program includes the following measures:
- carrying out of stationary field regime observations of qualitative composition of open pit, underground and surface waters;
- carrying out of areal hydrochemical and infrared survey of deposit for the purpose of research of seasonal changes of intensity of mineralized waters' inflow into the open pit;
- carrying out of observations of temperature mode of mineralized waters in special observation holes, placed directly in the area of crushing of western break;
- development of calculation of limit concentrations of indicators of underground waters, exhausted into water flow, taking into account its dilution capacity.
