Surface mining is the action of shaping external rock or cliff faces to prepare an area for tunneling, adjusting terrain for other uses or simply for aesthetic reasons. To mine on the surface, all adjacent corners of the tile must be clear of dirt.
Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an orebody, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
SURFACE MINING 'STRIP MINING' Definition quot;is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) 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.quot;

The mandated function of the Alabama Surface Mining Commission is to regulate the surface coal mining industry in Alabama and to ensure the reclamation of land which has been surfaced mined or which has suffered from the effect of underground coal mining.
Surface mining is a technique used to obtain bitumen from oil sands where the oil sands deposits are located fairly close to the surface. If the reserves are shallow enough, earth moving equipment can dig out oil sand for processing.
in surface mining is by truck and shovel combination. This operation is one of the key factor to reduce the cost of mineral production. This paper presents a complete However, in this case, it was seen as the first step in a well organized way to control the fleet produc tion applied to both the overburden and mineral extraction in surface
The Excellence in Surface Coal Mining Reclamation Awards are presented to coal mining companies that achieve the most exemplary coal mine reclamation in the nation. Past winners have demonstrated a commitment to sound mining practices and effective reclamation plans that enhanced beneficial post mining use of the land.
Mining is the process by which commercially valuable mineral resources are extracted (removed) from Earth's surface. These resources include ores (minerals usually containing metal elements), precious stones (such as diamonds), building stones (such as granite), and solid fuels (such as coal).
Surface Mining Methods. Surface Mining has traditionally been seen as Truck and Shovel operations. Today, the use of Continuous Surface Mining equipment is becoming more acknowledged as an alternative to traditional methods of surface mining.
Hidden inside a diamond forged deep within the belly of the Earth, scientists have found the first evidence of a mineral that's never been seen before.
Oct 30, 20180183;32;Surface mining is a method of mining used to extract minerals and metals which are near the surface of the Earth. There are three basic types of surface mining open pit
Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped. In best practice a detailed rehabilitation or reclamation plan is designed and approved for each coal mine, covering the period from the start of operations until well after mining
mining Surface mining It has been estimated that more than two thirds of the worlds yearly mineral production is extracted by surface mining. There are several types of surface mining, but the three most common are open pit mining, strip mining, and quarrying.
As can be seen, surface mining is much more advantageous than its counterpart. However, when an outcropping ore body stretches deep inside the Earth, surface methods can be used to begin the mining operation, which then need to be continued further by underground mining.
Beyond the dollar figures, Wood Mackenzie found that mining companies have seen a major gain by tapping into seawater and recirculated water social and political validation.

The Office of Surface Mining Reclamation and Enforcement (OSM) was created in 1977 when Congress signed the Surface Mining and Reclamation Act.This law established OSM to regulate surface coal mining and maintain uniform standards for coal mining on state and federal lands.

This time series of images of a surface mine in Boone County, West ia, illustrates why this controversial mining method is also called mountaintop removal. Based on data from Landsat 5, 7, and 8, these natural color images document the growth of the Hobet mine as it moves from ridge to ridge between 1984 to 2015.
Surface mining, including strip mining, open pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.
Mercury's surface is similar in appearance to that of the Moon, showing extensive mare like plains and heavy cratering, indicating that it has been geologically inactive for billions of years.Because knowledge of Mercury's geology had been based only on the 1975 Mariner 10 flyby and terrestrial observations, it is the least understood of the terrestrial planets.
