Drilling Machines
The type of rock drill used in mining drilling is generally determined by the hole diameter required and the mechanical properties, principally hardness, of the rock. A top hammer is commonly employed for drilling of holes less than 125 mm in diameter in all but the hardest rock, although a rotary cutting method may instead be used for soft rock.

SIMINE Haul Truck
Higher productivity. SIMINE truck drive systems provide high tractive forces at stall and enable the truck to move quickly, even on ramps, to transport more material in less time. SIMINE truck drive systems can be used with a trolley assist to overcome the limitations of engine power and increase speed on a gradient.
Underground Mining Methods and Equipment
The primary operations required in underground are rock breakage an d material handling. If the target is sufficiently soft (e.g., coal and rock salt), mechanical excavation utilizing continuous miners, shearers, ploughs/plows, and so on, can be employed. In contrast, drilling and blasting are usually employed when the ore is too hard for cutting.
Size Reduction UNIT 5 SIZE REDUCTION
Crushers do the heavy work of breaking large pieces of solid material into small lumps. A primary crusher operates on run-of-mine material, accepting anything that comes from the mine face and breaking it into 150 to 250 mm lumps. A secondary crusher reduces these lumps to particles perhaps 6 mm in size. Grinders reduce crushed feed to powder ...
