Numerical investigation on the caving mechanism with different standard deviations of top coal block size in LTCC

Numerical investigation on the caving mechanism with different standard deviations of top coal block size in LTCC

The size distribution of the broken top coal blocks is an important factor, affecting the recovery ratio and the efficiency of drawing top coal in longwall top coal caving (LTCC) mining panel. The standard deviation of top coal block size (δt) is one of the main parameters to reflect the size distri...
