Abstract

The article considers the hypothesis according to which one of the influences on spontaneous combustion of a coal waste dump is its geodynamic setting. Statistical data show that coal waste dumps located in geodynamically hazardous zones, i.e. at the interfaces of the Earth’s crust blocks, suffer from self-ignition more often than dumps set beyond the limits of such zones. The computer modeling of situation at a coal waste dump in the East Donbass reveals a cause-and-effect chain capable to explain this phenomenon. Air permeates into the dump from closely spaced underground mines through the geodynamically hazardous zones as the most permeable areas in rock mass. At fire-hazardous air flow velocity and temperature increment in the dump, its spontaneous combustion takes place. The gas mass transfer process intensifies and promotes further growth of the fire source. The modeling results can be used in coal waste dump planning and monitoring, as well as in combating spontaneous combustions.
