COMPARATIVE ANALYSIS OF MOISTURE SENSITIVITY INDEX TESTS FOR COAL MINE ROOF (2009)

Moisture deterioration of clay-rich roof rocks causes high numbers of roof falls in coal mines in humid summer months. Rocks with high moisture content are generally weaker and can further deteriorate when subjected to wetting and drying cycles. As a result, it is important to evaluate the moisture-sensitivity of roof rock prior to mining
