Protective coal pillars in underground mining are technological losses in the technology of extracting coal at the Angren deposit. During the mine operation, a significant part of the coal remains in the mine space. Extracting them is not possible with traditional energy-mechanical technologies. The paper considers a new extraction technology -energy-heat technological unmanned extraction of brown coal energy from the underground space of spent mine fields. The research results on the experimental sites of the technology of underground combustion of brown coal are presented. A simulation topological scheme of coal pillar combustion with a special chamber has been implemented. The burning rates of coal and heat fluxes in time are determined. The possibility of extracting the energy of coal in the form of a physical heat flow from the underground space of the mine to the daylight surface has been established.
