The paper presents results of quantitative estimations of gas bearing capacity and gas dynamic behaviour of shaly-carbonate and salt rock units along the geologic profile of the Starobinsky potash field between the III and IV potash horizons. Underground experimental studies of the gas bearing capacity and gas dynamic behaviour of the shaly-carbonate and salt unit rocks were conducted in the slopes opening the IV potash horizons in the mine field of the mine of the Second Mining Department of Belaruskali, JSC. The underground experimental research procedure provided for quantitative estimation of the following indicators: nonassociated gas bearing capacity, initial gas emission rate and gas pressure of rocks in the 12th, 10th and 8th shalycarbonate units, as well as the 11th and 9th salt units. Based on the underground experimental research data, a quantitative estimation of the gas bearing capacity and gas dynamic behaviour of rocks in the 12th, 10th and 8th shaly-carbonate units as well as the 11th and 9th salt units was performed. Identified were the most gas-bearing beds of rocks in the shaly-carbonate and salt rock units, as well as the pattern of changes in the gas bearing capacity and gas dynamic behaviour of rocks in the geologic profile between the III and IV potash horizons.
