Underground Mining Machinery Glossary Bibliography Biographical Sketches Summary The first section gives an overview of underground mining methods and practices as used commonly in underground mines, including classification of underground mining methods and brief explanations of the techniques of roomandpillar mining, sublevel stoping, cutandfill, longwall mining, sublevel
The underground mining methods we use include room and pillar, narrow vein stoping and largescale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them
MINE 411 Underground Mining Methods amp; Equipment Course Instructor: Prof. Raymond S. Suglo 1 UNDERGROUND MINING METHODS Introduction In mining, a method of extraction which will yield the largest net return (profit) is preferable. Two main criteria used in the selection of a suitable stoping method to mine a particular deposit are: Safety Economy The mining method chosen must
Block caving is essentially the underground version of openpit mining. Its the only underground mining method that can reach similar production rates to surface mining operations, up to over 100,000 tonnes per day. The method involves undermining an ore body, then allowing it to collapse under its own weight.

Blasting equipment is used for both underground and open pit mining operations and is known to be one of the most hazardous aspects of the job. For mining operations to be successful good blast designs are absolutely vital as poor practices and excessive explosives can result in damage to rock structures causing unwanted caving.
Major trends in improved underground mining include: (1) the opening of thick deposits by inclined shafts and removal of the ore to the surface by conveyors and poweroperated equipment; (2) the use of spiral access ramps to transport personnel, equipment, and materials to underground excavations; (3) the use of skips holding 50 tons and more; (4) the construction of concentrated horizons with
Highwall mining is a coal mining method for recovery of outcropped coal by mechanical excavation without removal of overburden. A continuous miner with single or multiple augers/cutting heads is operated underground and controlled remotely by crew located outside.

The principal means of access to an underground ore body is a vertical opening called a shaft. The shaft is excavated, or sunk, from the surface downward to a depth somewhat below the deepest planned mining horizon. At regular intervals along the shaft, horizontal
#0183;#32;Underground mining; Underground mining is a method of mining that extracts ore from underneath the earths surface. The entry from the earths surface to the underground mine may be created via a horizontal or vertical tunnel (also known as adit, shaft, and decline).

section describes underground mining equipment, with particular focus on excavation machinery such as boomheaders, coal cutters, continuous miners and shearers. 1. Underground Mining Methods Classification of Underground Mining Methods Mineral production in which all extracting operations are conducted beneath the ground surface is termed underground mining.
#0183;#32;What equipment is used for mining? In traditional surface and underground mining, hammers and chisels with pickaxes and shovels are used. Minecarts are used to move ore and other materials in the process of mining. Pans are used for placer mining operations, such as gold panning.
Four main methods of mining are available: underground, open surface (pit), placer and insitu mining. Underground mines are more expensive and often used to reach deposits that are deeper. Surface mines are usually used for deposits that are shallower and less valuable.
