The article presents the research results on gas content and gas dynamics of rocks characterized using measurement stations installed at the intersection of underground openings and the tectonic fault in Krasnoslobodsk mine, Mine Management 2, Belaruskali. The geological structure of the fault zone is described, and the gas content of this area is unstudied. The field research procedure for underground investigations in the course of mining across the fault zone is presented. The procedure is based on the instrumental monitoring of gas emission from holes with a diameter of 42 mm, drilled in a cross-entry, with simultaneous free gas sampling. All in all, 8 measurement stations were uniformly spread along the fault zone intersected by the cross-entry. The accomplished research proves total degasification of rocks mass within the fault zone and zero conditions for sources of hazardous gas-dynamic phenomena.
