subsurface mining Definition Subsurface mining is the extraction of minerals and ores from underground. It consist of digging shafts into the earth for ore. ... The 3 main types of sub-surface mining are quarrying, solution mining, and long wall mining. All use different equipment and techniques. Full transcript.
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.

A type of subsurface mining where the excavation of a series of "rooms" into the mineral bed, leaving "pillars" or columns of coal to help support the mine roof. The mineral is broken up by explosives, loaded onto a vehicle by a mechanized loading machine.
Underground mining. Underground or "deep" mining consist mostly of two methods - room-and-pillar and longwall mining. In room-and-pillar, coal deposits are mined by cutting a network of "rooms" into the coal seam and leaving behind "pillars" of coal to support the roof of the mine.

These mining categories are: strip mining, open-pit mining, mountaintop removal, dredging and high wall mining. All methods of surface mining will remove the waste material, or overburden, above the desired resource. Surface mining is often preferred to sub-surface (underground mining) by mining companies for several reasons.

BLM National – Minerals & Mining – BLM Arizona. The BLM's mineral programs can be categorized into three major mineral resource types: locatable, leasable and salable minerals. In fact, the BLM administers approximately 17.5 million subsurface acres, and supervises mineral operations on about 73,000 acres of Native American lands across the ...
Subsurface mining: Commonly used for zinc, lead, nickel, tin, gold, copper, diamonds, phosphate, salt, coal and uranium. Is used when the resources occurs in concentrated pockets deep underground. Is used when the resources occurs in concentrated pockets deep underground.
Simply said Mining is the extraction of valuable minerals or other geological minerals from earth.Generally there are two types of Mining i,e; Surface Mining, Sub-surface Mining(Underground) Mining.Most of the places Surface Mining is quite common in practice.

Placer mining. Placer mining is a way of obtaining mineral and metal resources from loose river sediments. The water helps sift the valuable resources (such as gemstones or gold) from the sand, mud, and gravel in the riverbed. Placer mining occurs on a much smaller scale than other methods of surface mining.
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.

ChaCha Answer: The 3 main types of sub-surface mining are quarrying, solution mining, a… Mining – Wikipedia, the free encyclopedia Mining techniques can be divided into two common excavation types: surface mining and sub-surface (underground) mining.
Continuous mining is the most prevalent form of underground mining, accounting for 56% of total underground production. In continuous mining, a machine known as a continuous miner cuts the coal from the mining face, obviating the need for drilling and blasting. Another type of continuous underground mining is called longwall mining.
It is "the most dangerous type of mining there is," said Tony Oppegard, a former top federal and Kentucky mine-safety official who is now a private attorney in Lexington, Ky., representing miners.
