fulfillnent of the requirements for the degree of Doctor
of Philosophy, 1992 / The self-heating of coal is a problem which concerns the mining industry not only in South Africa, but also in
many other countries. This thesis deals with the contouring of spontaneous combustion liabilities (WITS-ERAC index values) of different seams at the Durban Navigation Colliery and the relationship between the WITS-EHAC index values and the properties of the coal samples. In the determination of the spontaneous combustion liabilities 58 different coal samples were tested with an ignition-temperature test apparatus, crossing-point temperature tests and differential thermal analysis were conducted simultaneously.
