Abstract

Using gray correlation analysis method,the paper researched the correlation degree of gases generated from temperature programmed test of coal spontaneous combustion,obtained generalized comprehensive correlation degree of index gases in different stages of coal temperature.Then,the index system of forecasting coal spontaneous combustion is established and can accurately predict the degree of coal spontaneous combustion in Heyang №1 coal mine.The result has important theoretical significance for preventing coal spontaneous combustion.
