Technologies in Exploration, Mining, and Processing
Hydraulic mining uses water power to fracture and transport a bench of Earth or gravel for further processing. Hydraulic mining is used for placer deposits of gold, tin, and other metals. Surface mining equipment is similar to construction equipment (e.g., scrapers, bulldozers, drills, shovels, front-end loaders, trucks, cranes, draglines).

16.2: Mining, Processing, and Generating Electricity
Mining. Coal is extracted by two principal methods, of which there are many variants: surface mining or subsurface mining. Surface mining uses large machines to remove the soil and layers of rock known as overburden to expose coal seams that are close to the Earth's surface (figure (PageIndex{a})).Strip mining is a type of surface mining in …

Coal
Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.
