... coal mining scenario. The vertical stress, total volume of gas emission, and incremental energy release rate ( ERR ) were determined from a coupled geomechanical and gas flow model to represent longwall top coal caving mining practiced at Coal Mine Velenje. The values were fed into the PRA framework...
