Forecasting spontaneous combustion of coal in underground coal mines by index gases: A review
Journal of Loss Prevention in the Process Industries, 2019Spontaneous combustion of coal in underground coal mine is a long-standing thermal dynamic hazard. The hazard is harmful in diverse aspects: causing loss of coal resource, raising safety concerns, and giving off noxious/greenhouse effect gases. Detection
