Known also as "opencast mining", openpit mining is the most common type of surface mining. Openpit mines are enormous holes in the ground; created and increased by blasting and drilling rocks apart.
Openpit mining, also known as opencast mining, opencut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from extractive methods that need tunneling into the earth.

(1) strip mining, open pit mining, and contour mining operations, (2) quarrying, (3) the mining .
Openpit mining is much safer than shaft mining. In underground mining, the threat of a cavein or release of toxic gas is a constant concern. When shaft mining was the most common method of ore extraction, thousands died in caveins, gas events and accidents involving equipment. In 1907 alone, more than 3,200 deaths related to mining occurred.
Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
Mining equipment selection. In general, most contemporary surface mining operations rely on mobile drill rigs, hydraulic shovels, frontend loaders, scrapers and haul trucks to extract ore and initiate ore processing. The larger the mine operation, the larger the capacity of equipment required to .
Full Answer. Surface coal mining, for example, has contaminated more than 5,000 miles of streams in the eastern United States, impacting aquatic ecosystems and public drinking water supplies. Although surface mining reduces production costs and poses fewer health dangers to miners compared to underground mining,...
Surface mining. Surface mining includes strip mining, openpit mining (UK: open cast mining) and mountaintop removal mining. It is mining in which soil and rock overlying the mineral deposit are removed. It is the opposite of underground mining, in which the overlying rock is left in place, and the mineral removed through shafts or tunnels.
28 · Openpit mining causes changes to vegetation, soil, and bedrock, which ultimately contributes to changes in surface hydrology, groundwater levels, and flow paths. Additionally, openpit produces harmful pollutants depending on the type of mineral being mined, and the type of mining .
This mine is an open pit mine producing 5,000 tonnes ore and 5,000 tonnes waste per day. Rock characteristics for both ore and waste are typical of those of granite or porphyritic material. Operating conditions, wage scales, and unit prices are typical for western mining operations.

Most open cast mines in the United States extract bituminous coal. In Canada (BC), Australia and South Africa, open cast mining is used for both thermal and metallurgical coals. In New South Wales open casting for steam coal and anthracite is practiced. Surface mining accounts for around 80 percent of production in Australia, while in the US it is used for about 67 percent of production.
