Improving coal recovery from longwall top coal caving

This paper develops a series of methodologies to improve the recovery rate from longwall top coal caving. Cavability of top coal is the most essential indicator to estimate the recovery rate. Some influencing factors of cavability such as unconfined compressive strength, abutment pressure and thickn...
