3 major types of subsurface mining 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.
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.

Types of surface mining . Strip mining: This process involves the method of extracting the mineral by removing soil and rock which are deposited on the surface.Coal and Lignite are the two principle minerals that are extracted through this method.
The two main types of mining are surface mining and underground mining. Mining is further divided into several other categories including room and pillar mining, slope mining, block caving, quarrying, open-pit mining and in situ mining. Surface mining involves stripping surface vegetation, dirt ...
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.

Mining is the process of extracting minerals like gold, silver, copper, nickel and uranium (metallic) and salt, potash, coal and oil (nonmetallic) formations that concentrate naturally in the earth. 3.
Subsurface mining is used where the material is in veins deep beneath the surface, or obstructed (by rock layers, water tables, or other strata) in a way that make surface access impractical. Early mines used existing caves, but technology has brought increasingly deep and complex drilling to reach veins of coal or metal ores.

Subsurface Mining. When mineral ores are too deep to get at with the surface mining techniques, subsurface mining methods are used instead. An advantage of subsurface mining is that it disturbs much less land than surface mining. In fact, it disturbs less than one-tenth the amount of land as surface mining.
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 state.

The method used depends on the type of mineral resource that is mined, its location at or beneath the surface, and whether the resource is worth enough money to justify extracting it. Each mining method also has varying degrees of impact on the surrounding landscape and environment.
There are two types of room and pillar mining–conventional mining and continuous mining. Conventional mining is the oldest method and accounts for only about 12% of underground coal output. In conventional mining, the coal seam is cut, drilled, blasted and then loaded into cars .

Dec 02, 2010· MaKayla Ray, The four types of mining are.. 1) Subsurface mining- located below Earth's surface. 2) Surface mining- located close to Earth's surface. overlying rock material is stripped away to reveal the mineral deposits.
Surface mining When an ore bed has been located relatively close to Earth's surface, it can be mined by surface techniques. Surface mining is generally a much preferred approach to mining because it is less expensive and safer than subsurface mining.
Mining techniques can be divided into two common excavation types: surface mining and sub-surface (underground) mining. Today, surface mining is much more common, and produces, for example, 85% of minerals (excluding petroleum and natural gas) in the United States, including 98% of metallic ores.
Types of Subsurface Mining - A form of coal mining where a long wall of coal is mined into a single slice, typically about 0.6-1.0 meters thick. - The coal is cut from the coalface by a machine called the shearer or power loader.
