Abstract
This article provides information on ensuring safety at coal mines by analyzing existing coal mining facilities. Information on the Angren coal mine is also given. It is shown that there are no accurate methods for determining the location of fires in order to increase the efficiency of spontaneous combustion prevention by supplying liquid compositions such as water and clay pulp flowing down the formation soil. Measures have been proposed to suppress spontaneous combustion centers, nitrogen is being increasingly used, the supply of which ensures volumetric processing of the collapsed mass and allows reducing the oxygen concentration in the mined-out space.
