coal mining basins
Coal Basin - an overview | ScienceDirect Topics
Romeo M. Flores, in Coal and Coalbed Gas, 2014 Influence of Basin Rebound. Coal basins rebound by uplift, which expends tremendous amounts of stress, which is subsequently relaxed and lessened by erosion. This process permitted development of cleats or fractures especially in shallow coal beds. The cleats formed in coal by basin rebound are prone to develop at
