Borehole Mining, Underground Mining, Mining Techniques ...
Borehole mining is done to mine many industrial materials like uranium, iron ore, quartz sand, gravel, gold, diamonds and amber. It is a remote controlled method of underground mining. It is also used in exploration, oil, gas, and water stimulation.
Borehole mining - WikiMili, The Free Encyclopedia
Borehole Mining (BHM) is a remote operated method of extraction (mining) of mineral resources through boreholes based on in-situ conversion of ores into a mobile form (slurry) by means of high pressure water jets (hydraulicking). This process can be carried-out from land surface, open pit floor, und
Types of Drilling Methods used in Mining | Boring | Mining ...
Method # 1. Percussive Drilling: In this method which is the oldest one of drilling, the hole is drilled by striking a number at short in intervals on the rock by a chisel-type tool and between the blows the tool is rotated slightly. The rock is chipped away with each blow and a circular hole is formed.
In-Situ Leaching & Borehole Mining
The Bureau is not alone in evaluating borehole mining techniques for exploiting mineral deposits. Continental Oil Co., and FMC have both evaluated the technique for mining phosphate deposits. Marconaflo has tested its borehole mining method in remining or moving tailings as well as direct extraction of uranium deposits.
Borehole Mining - Kinley Exploration : Kinley Exploration
No longer a science project, borehole mining is proving itself as a workable technology that can be applied to a number of industries. Hydraulically jet-cutting a cavern of rock 20 feet in diameter from a drilled bore hole allows this system to recover resources previously uneconomical for open pit or underground mining operations.

Mining - Solution mining | Britannica
All techniques begin with the successful drilling of a borehole to the top of the salt formation. The well is cased, or lined, with one or more pipes of steel or another material, and the hole is then extended to the bottom of the formation. At this point any one of four different production configurations is used.
Borehole - Wikipedia
The machinery and techniques to advance a borehole vary considerably according to manufacturer, geological conditions, and the intended purpose. For offshore drilling floating units or platforms supported by the seafloor are used for the drilling rig.

Hydraulic Mining Methods. Although hydraulic mining was introduced in the United States before the turn of the century, it has not gained the degree of acceptance found in other countries such as Russia, China, Germany and Canada.
Jet Boring/Borehole Mining | RCS Group of Companies
Jet boring – also known as borehole mining, jet mining or underground hydraulic mining, is a remote controlled process utilizing conventional drill rigs to drill a bore hole in the earth to a designated depth. Normally this borehole is cased to the top of the formation to be jetted.

Nov 02, 2011 · Surface mine - A mine in which the ore lies near the surface and can be extracted by removing the covering layers of rock and soil. Almost all surface mining operations are exposed to the elements and require no roof support. 2 February 2016 5Prof. Dr. H.Z. Harraz Presentation 6.
Mining Techniques | Geology for Investors
Jun 14, 2013 · The most common surface mining technique is open-pit mining (Figure 1), where a commodity is extracted via an open pit in the ground. This is an extremely cost effect way of removing a resource because large quantities can be removed with minimal effort. Other surface techniques include quarrying and strip mining.
Well logging | mining | Britannica
Well logging, field technique used in mineral exploration to analyze the geologic formations penetrated by a drill hole. If the hole has been drilled by using coring techniques, the core provides a visual record of the formations and rock types encountered. The description (log) of the core provides ...
