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. 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.
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.
IN.gov – DNR – Permits. When conducting the pre-mining inventory, a post-mining land use must be considered and proposed so it may be designed into the mine operation and reclamation plan.
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.
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.
There are several types of surface mining, and strip mining ... subsurface mining advantages disadvantages. advantages and disadvantages of subsurface … · What are advantages and disadvantages of subsurface mining.

2015-10-29· 019 - Mining In this video Paul Andersen explains how mining is used to extract valuable minerals from the Earth's crust. Surface and subsurface mining are used to extract ore which is then processed.
Type of mining used where the terrain is flat. An earthmover strips away the overburden, and a power shovel digs a cut to remove the mineral deposit. After removal of the mineral, the trench is filled with overburden, and a new cut is made parallel to the previous one. …
what are the 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 can be done in many ways with a vast number of terms to describe each type. However all types involve digging tunnels or shafts to access a resource that is too far below the surface or too spread out to use a surface technique and remain economical. The tunnels that are offshoots of the main shaft are termed "drifts". The commodity is extracted in the subsurface and then ...
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.
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.
As a leading global manufacturer of crushing and milling equipment, we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant.
SUBSURFACE MINING-If the depth of mineral is more from the surface or it is not economical to carried out mineral then a Vertical shaft,Incline shaft,decline and tunnel type design known as Adit are made for reach the deposit and taking out mineral easily simply called as subsurface mining or underground mining.It's depth up to 200 to 1–2 km.There are lots of mine in world whose depth up ...
Subsurface pipes can be used to drain heavy (clay) poorly drained soils successfully but their spacing would need to be so close together that they are uneconomic in extensive farmland systems.
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.
Subsurface geology is the study of the physical properties and location of rock and soil found below the ground surface. One of the most valuable reasons for learning about the subsurface is understanding the materials below man-made structures.
Subsurface mining is actually less disruptive to the earth and produces less waste than surface mining, but it's also much less effective and more dangerous. Many workers die in mine collapses ...

Sub-Surface mining is the extractions of ores & minerals, which lie underground There are three types main of sub-surface mining -Quarrying used to extract minerals
Surface and Subsurface Methods of Mineral Exploration . The major motive in exploring the earth's surface and its interior is scientific curiosity or the desire to understand better the nature of the Earth.
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.
What is subsurface mining - The Q&A wiki . Subsurface mining, is the extraction of ores and minerals, which lie underground.
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 …
Subsurface mining is the extraction of minerals and ores from underground. It consist of digging shafts into the earth for ore. One con would be that the mines make a lot of hazardous acid mine drainage. Machines Surface mining techniques don't work for extracting all valuable geologic resources
