It is well-known that geological prospecting and absorption holes are one of the ways of possible water income into excavations in the time of underground mining of mineral deposits. Exact location of these deposits is important for efficient and safe carrying out of mining operations near the pillars. Starobinsky potassium salts deposit is developed by «Belaruskali» JSC. In the last years, usage of geophysical methods was started at Starobinsky deposit for definition of location of geological prospecting boreholes at the level of productive horizons. The carried out researches made it possible to define the georadiolocation methods (using low-frequency georadars) as the main methods for definition of boreholes' location. Seismic or electrical prospecting research methods can be also used as additional methods of exploration of boreholes, depending on mining and geological situation, geophysical prospecting conditions and structure of wells. Distant (geophysical) research methods are used for definition of exact location of boreholes at the level of developed layer of minerals from excavations of functioning mines of Starobinsky potassium salts deposit. These methods make possible to provide the carrying out of safe mine operations and considerable decreasing of losses of mineral in protective pillars. Developed methods of exploration of boreholes can be applied at other mineral deposits, which carry out the underground mining of deposits. Application of these methods is necessary for provision of safe conditions of mining operations near water protection pillars of geological prospecting wells.
