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.
Mining accidents occur in the process of mining metals or minerals. Thousands of miners die from mining accidents each year, especially in the process of coal mining and hard rock mining. Generally speaking, surface mining usually is less hazardous than underground mining.

Coal in Wyoming is uncovered and removed by large machines in a process called surface mining. Before the coal can be removed from the ground, the topsoil and dirt above it is removed using scrapers. This soil is usually removed ahead of the pit and carried behind to place on top of reclaimed areas or backfill.
One of the most obvious (albeit perhaps least harmful) environmental effects of coal mining is noise pollution. Coal mining is a loud, day- and night-long process that disrupts the lives of those in the surrounding communities, reduces the quality of life and can go on for decades.
