Mining Machinery
• The machinery for underground mining need to fulfil the following requirement:
1) Higher strengths of main parts (i.e.) higher factor of safety.
2) Special electrical and mechanical devices for preventing breakdown
under overloaded condition for varying working conditions
3) Flame-proofing
4) Low height for working in thin seams
5) Control of exhaust of diesel engines to preclude mine air contamination and
chances of igniting firedamp in coal mines
6) Materials used for the components must withstand the corrosive environment of
the mine face
