Identifiion and control of spontaneous combustion of coal .
· Spontaneous combustion of coal is a natural hazard during mining. In China, more than 60 % of cases of spontaneous combustion of coal in China result from coal pillars in goafs. In this paper, the plastic deformation of a coal pillar was simulated and, based on the simulated vertical and horizontal displacement, the distribution of surface porosity was deduced.
Prediction of Coal Spontaneous Combustion Temperature ...
The early prediction of coal spontaneous combustion can be realized by detecting CO gas.
