Acid Producing Potential of the Various Lithic Units Associated with the Mining of Coal

摘要

A collection of the seven different potentially toxic lithotypes encountered in the mining of coal were collected for five coals in 18 mines over a 5 county area in northern West Virginia for a total of 89 samples. Each sample was subjected to total sulfur analysis and to the soxhlet extraction/oven reoxidation procedure devised by the authors for the evaluation of an acid production rate constant, alpha. The data show that the samples with the lowest sulfur contents have the highest acid production rate constants.
