The Mining Process. 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.
Open Pit Mining is an excavation carried out on the surface of land that is intended to take the materials in the ore minerals in the soil surface. The main objective of the mining activities are taking deposits of parent rock, making it easy to be transported and processed within the next process further.

Surface mining is used to obtain mineral ores that are close to Earth's surface. The soil and rocks over the ore are removed by blasting. Typically, the remaining ore is drilled or blasted so that large machines can fill trucks with the broken rocks.
Mining the Coal. Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Many U.S. coal beds are very near the grounds surface, and about two thirds of coales from surface mines.
