The Mining Process – Waihi Gold

The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

What Is Coal Mining - Some Interesting Facts

The two major schools of coal mining are surface mining and underground mining. To qualify for surface mining, the coal seam must lie within 60 metres of the surface. The miners’ job is to remove all of the ‘overburden’ – the cubic tons of rock, soil and trees above the coal seam -and expose the coal layer for extraction.
