A wide variety of techniques have been applied to gain insight into the processes that govern the self-heating of coal. These include oxidation mechanisms, ranking the propensity of different coals to self-heat, and the detection and suppression of self-heating. A frequent weakness in the literature about the kinetic data of self-heating systems is the absence of error estimates from regression analysis and the associated constraints on the reliability of the data for modeling. In addition, experimental and numerical work is needed to evaluate the methods used to acquire the kinetic data. Moist coal in coal mines and stockpiles has very different combustion characteristics than those predicted on the basis of dry testing. Consequently, methods for ranking the propensity of coal to spontaneously combust in actual mining conditions need to be developed.

The “sedimentary cover” refers to the stratified rocks of youngest Proterozoic and Phanerozoic age that rest upon the largely crystalline basement rocks of the continental interior. The early chapters of the volume present data and interpretations of the geophysics of the craton and summarize, with sequential maps, the tectonic evolution of the craton. The main body of the text and accompanying plates and figures present the stratigraphy, structural history, and economic geology of specific sedimentary basins (e.g., Appalachian basin) and regions (e.g., Rocky Mountains). The volume concludes with a summary chapter in which the currently popular theories of cratonal tectonics are discussed and the unresolved questions are identified.
