Loading: In early days, Coal production was done manually basket loading with the help of picks. In beginning manual cutting was phased out by solid blasting and coal cutting machines. Now coal cutting machines have been phased out and these have been replaced by Side Discharge Loaders (SDLs) and Load Haul Dumpers (LHDs).

6. (1) Mechanical attack The application of mechanical energy to rock can be performed basically in only one of two ways: by percussive or rotary action. Combining the two results in hybrid methods termed rollerbit rotary and rotarypercussion drilling. The mechanical category, of course, encompasses by far the majority (probably 98%) of rock penetration applications today.
