【Abstract】 hrough analyzed the changing laws of the composition of different coals’ gas along with the temperature raising to the lignite from Liangjia Mine and Beizao Mine of Longkou Mining Group, and the sharp flame coals from Sanhejian Mine of Xuzhou Mining Croup , and Bituminous coal from Zhangshuanglou Mine ,this article proposed different colas’ spontaneous combustion forecast gas markers and reliable index which can predict the coal’s spontaneous combustion. This have great significance on preventing coal’s spontaneous combustion and mines’ safety product .更多还原
