Spontaneous Coal Combustion Part 2: Chemical Inhibitors This blog post is part two of a three-part series on spontaneous coal combustion. In this post, we focus on preventative measures and controls, and in the upcoming post we'll take a look at best practices.

Spontaneous combustion results from self-heating which is caused mainly by the oxidation of coal and other carbonaceous materials. If the heat generated by this reaction is trapped, such as in a spoil pile, the temperature of the material will begin to rise and if unchecked may ultimately ignite; i.e. spontaneously combust.
