Spontaneous combustion of coals and coal-shales

International Journal of Mining Science and Technology, 2018
Spontaneous combustion of coal is a well-known phenomena around the globe. Apart from the coal itself, burning coal-shales is becoming a problem in the South African coal mines.

Spontaneous Combustion of Coal (I)

Fire Science and Technology, 1985
Thermogravimetry of coal has been carried out by changing the oxygen concentration of the heating atmosphere, and the effect of oxygen in the concentration of 1-60% flow gas has been discussed based on the thermogravimetric curves. The kinetic parameters of exothermic oxidizing reaction of coal in the thermogravimetric, which has one of the critical ...

Estimation of greenhouse gas emissions from spontaneous combustion/fire of coal in opencast mines – Indian context [PDF]

, 2016
There are a significant number of uncontrolled coal mine fires (primarily due to spontaneous combustion of coal), which are currently burning all over the world. These spontaneous combustion sources emit greenhouse gases (GHGs). A critical review reveals
