Environmental Consequences of Coal Mines of Kuznetsk Basin by the Gas- Dynamic Factor and Hazard of Endogenous Fires at Dumps

Abstract

Existing prediction methods of environmental consequences in territories of mining leases of liquidated mines require the deeper scientific substantiation for the
implementation of effective algorithms of environmental monitoring. Therefore, investigations devoted to monitoring of environmental consequences of closing
the mines of the Kuznetsk basin are urgent. The goal of studies was to refine the regularities of aerogasdynamic and thermal processes, the effect of which on the
environment is caused by the liquidation of mines, in order to improve the environmental monitoring system in spent territories of the Kuznetsk basin. A procedure
for the prognostic evaluation of the influence of methane liberation from spent spaces of liquidated mines to the Earth surface is substantiated. The dynamics of
characteristics affecting the environmental safety is evaluated based on computational experiments and situation analysis. The evaluative procedure of self-heating
of coal accumulations on the surface of rock dumps is proposed. Heat liberations are modeled by the source with the power spatially varying according to the
exponential law
