Substantiating topicality of injectable localizing and deactivation of coal seams prone to endogenous spontaneous combustion

Abstract

The analysis for possible development of endogenous fires in coal seams prone to oxidation and spontaneous combustion is done. The coal free surface area is taken as a forecasting criterion for estimating the state of the zones of broken condition. The effectiveness of applying fracture plugging (cementing) technology for injectable localizing and deactivation of the massif is substantiated. The conception for further studying of the processes for controlling physical and chemical characteristics of a seam considering native properties of coal is formed.
