Subsurface Mining Definition

Subsurface mining is the removal of deposits from the earth by drilling underneath layers of rock and dirt. These deposits are difficult to reach from the surface and require the drilling of vertical or horizontal shafts for access. The shafts are reinforced with supports before workers access the tunnels.

Answer and Explanation: Subsurface mining is when the materials being mined are below the surface of the Earth. This means that the mining must occur below the surface as well, because the resources cannot be accessed from surface level. Subsurface mining is done by building reinforced tunnels down from the surface to the place where the resource is located.

Subsurface mining operations don’t create the visible changes in the landscape that surface mining operations do, but the conditions of subsurface mines are extremely hazardous for the working miners. The potential for accidental cave-ins, explosions, and fires is high.

The Definition. As stated by GreatMining.com, it’s: Surface mining is a form of mining in which the soil and the rock covering the mineral deposits are removed. It is the other way of underground mining, in which the overlying rock is left behind, and the required mineral deposits are …

Transcript of Subsurface Mining and its Environmental Impacts. Subsurface mining consists of digging tunnels or shafts into the earth to reach buried mineral deposits. This form of mining is most commonly used for zinc, lead, nickel, tin, gold, copper, diamonds, phosphate, salt, coal, and uranium.

Oil Mining, Subsurface a method of petroleum extraction that is based on the digging of a system of underground mining excavations. The method is used to mine pools containing high-viscosity oils, or bitumens, and heterogeneous pools of medium-viscosity oil that are no longer productive by other methods. Oil may be mined either by washing or by drainage ...

Subsurface Mining Environmental impacts Has much less of an impact than surface mining, but can cause cave ins, miner have health issues, subsidence and Acid mine drainage when rainwater seeps into a mine and aerobic bacteria react with iron sulfide to create sulfuric acid.

APES mining vocab. Form of mining used on hilly or mountainous terrain. A power shovel cuts a series of terraces into the side of a hill. An earthmover removes the overburden, and a power shovel extracts the coal, with the overburden from each new terrace dumped onto the one below.

Subsurface mines are probably what you envision when you think of mining: systems of tunnels and vertical shafts with elevators to take miners underground where they can retrieve the valuable resources.

Environmental Impacts Laws - Details about how the topsoil will be affected and how it will be replaced must be stated before mining begins. - All affected water must be processed and cleaned before leaving the mining site. - Procedures for public notice, public participation and

Sorry about my last answer-subsurface was the question! Pros: very little disturbance above ground , mining can last in the same area very long periods of time,which stabilizes a local economy. Mining can recover valuable minerals that are too far under cover to be mined any other way.

Ecological effects of subsurface mining Surface mining techniques don’t work for extracting all valuable geologic resources. Diamonds and most metal ores, including gold, require extensive subsurface mines to access the rocks with these resources in them. Subsurface mines produce

Subsurface mining. The removal of oil and natural gas by drilling into Earths surface are well-known examples. Certain water-soluble minerals can be removed by dissolving them with hot water that is piped into the ground under pressure. The dissolved minerals are then carried to the surface.

Surface mining, method of extracting minerals near the surface of the Earth. The three most common types of surface mining are open-pit mining, strip mining, and quarrying. See also mining and coal mining.

Surface and Subsurface Methods of Mineral Exploration. With conventional approaches and tools, only a very limited portion of the subsurface regions of the Earth can be studied. Investigators can drill into only the uppermost crust, and the high cost of drilling severely limits the number of holes that can be dug.

Subsurface mining techniques may not be possible in a very weak and unconsolidated host rock. Cost associated with stabilizing drifts and risk of collapse may over shadow any potential revenue. On the other hand, unconsolidated and soft host rock is ideal for open-pit style mining because it …

In subsurface mining, a long tunnel is created either horizontally or vertically. The tunnel walls are reinforced with wood and ventilation shafts are created to provide air to the miners underground.

Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments. In-situ mining, which is primarily used in mining uranium, involves dissolving the mineral resource in place then processing it at the surface without moving rock from the ground.
