CDC Mining Topic Spontaneous Combustion NIOSH

Apr 28, 2020· Spontaneous combustion continues to pose a hazard for U.S. underground coal mines, particularly in western mines where the coal is generally of lower rank. The risk of an explosion ignited by a spontaneous combustion fire is also present in those mines with appreciable levels of accumulated methane.

Spontaneous Coal Combustion Part 1: A Burning Mystery

India has the largest concentration of coal fires, and it is estimated that 80% of those fires started due to spontaneous combustion. Indian coal fires were first documented in coal fields located in Raniganj back in 1865. In addition, mines in Jharia, Jharkhand are famous for their rich coal resources, but records show nearly 70 fires have been burning for over 100 years dating back to 1916.

Spontaneous Combustion Description Introduction

However in coal mines, coals spoken of as being liable to spontaneous combustion are those coals which will develop to an open fire under specific conditions. Many seams will not reach this point. When spontaneous combustion occurs, there is an initial stage where the temperature is rising but no burning in the normal sense is taking place.
