Abstract: The object of the research is the existing methods and diagnostics means of the condition of peat deposits and suppression of peat fires. The author carried out a system analysis of the problems connected with formation and use of peat with due consideration of its increased fire danger. The article shows that suppression of peat fires with water makes it impossible to exploit the peat fields. The author offers a model of the automated complex of detection, prevention and suppression of fire with the existing gas peat trunks which are constructively improved and turned to thermoelectroprobes that allow to suppress the process of self-heating of peat by means of atmospheric nitrogen received using the air separation method. The methodology of the research is based on a new domestic method of peat "nitrating" protected by the patent of the Russian Federation for inventions. The novelty of the research lies in synthesizing a diagram of vertical electric sounding of the peat bog (known since the last century) by means of appropriate finishing of gas-peat trunks to thermoelectroprobes in the course of development of the automation model, in addition to the thermal location and suppression of the center of self-heating of peat using gas-peat trunks (the thermoprobes offered in the specified patent of the Russian Federation).
