This article proposes a method for the calculation of the minimal distance between outfalls of boreholes at permafrost. Based on the analysis and comparison of calculation results, the authors show that the use of heat insulation in the borehole’s construction essentially cuts the minimal distance between outfalls. In these cases, the economy of the construction materials in fill area may run up to 30-50%. For reasonable calculations of the thawed area parameters near the group of boreholes, it is necessary (as opposed to the current practice) to take into account the total heat of the boreholes. This factor is required for all permafrost regions; moreover, as the inaccuracy in the calculations, connected with disregard of this factor, will increase when moving to the North.
