Susceptibility to Combustion
Some materials, especially old colliery discard material, may contain sufficient carbonaceous material to present a risk of combustion. Combustion in old tips can arise in two ways. Material near the surface may catch fire as a result of surface fires started either accidentally or deliberately, such as the burning of refuse. Material deep within the tip can spontaneously combust as a result of heat generated by the gradual degradation of carbonaceous material within the tip. In both cases the risk depends on the proportion of combustible material present and, in the case of deep spontaneous combustion, the proportion of air voids that are a source of oxygen, allowing burning to take place. The potential for combustion is normally assessed by measuring the calorific value of the material, and guidance is given in terms of the calorific value test.
