The paper analyses engineering and geocryological conditions of the Elginsky coal deposit in terms of their impact on the development technology. Based on the analysis of the temperature and humidity conditions of rocks at the Elginsky deposit, it was established that the blasted rocks may re-freeze during the drilling and blasting stage, which is also confirmed by practical experience. Groundwater is present throughout the field, and the water content of the lower levels in the central part of the deposit may impede mining operations and require advance measures to lower the water table. Isomorphic maps of permafrost and glacial sediments in the northwestern part of the Elginsky coal field were created using the Mineframe software. Distribution patterns of these zones were established within the rock mass along the strike and in depth, which will make it possible to make reasonable adjustments to the field development technology.
