Abstract: One of the complicating factors in the development of the Yaregskoe field using the thermal mining method is the regular breakthrough of the heat carrier into the mine workings. Despite the fact that in the thermal mining system, steam is injected into the seam at a distance from the active mine workings, this leads to uncontrolled breakthroughs. The main problem with the operation of oil mines is the low rate of heat carrier injection due to steam breakthroughs into the tuffite level workings, which limits steam pumping into the steam-injection wells. The main disadvantage of the thermal mining system is the increase in the temperature of the mine atmosphere and rock mass, heating the seam at a distance of up to 350 m from the mouth of the underground steam-injection wells. The increase in the temperature of the mine atmosphere due to steam breakthroughs leads to a reduction in the time that personnel can spend in the mine workings and disrupts the operation of the wells. To continue operating the areas where the heat carrier has broken through, steam injection is limited, which in turn leads to a decrease in oil production rates. One of the main approaches to solving the problems of heat carrier injection and preventing steam from escaping into field tunnels is the development of compositions for insulating steam breakthrough points in existing oil mine workings, which will reduce the air temperature in the workplace. Reducing the negative impact of steam breakthroughs into mine workings is a pressing and important task in thermal mining. This article presents the results of studies of the fracturing of rocks at the Yaregskoye field, tests to determine the compressive strength, reaction/setting time, and material consumption for the formation of 1 m³ of mixture composition for the elimination of steam outlets in field drifts. The effectiveness of using insulating compounds in the fractured rocks of the Yaregskoye field has been proven, which is explained by the increased resistance of mine workings to heat carrier breakthroughs, since the bonding solution will penetrate the cracks in the rock mass to a depth of 0.5-0.8 m and withstand the effects of overheated steam.
