Description of mining methods (step by step)

Primary Mining Method Sequential grid down dip. Information. To deal with ground pressures, a V-shaped mining sequence is utilized. The main advantages of the sequential down dip method are the very low energy release rates, which make backfilling unnecessary, and the allowance for the physical separation of rock transport from men and materials.
