Surface mining planning and design of open pit mining
· Scrapers are sometimes used in special situations. Large bucketwheel excavators of the kind used in European coal mines have not been applied to metal mining, because this equipment is best adapted to softer bedded, relatively flatlying strata. Many factors govern the size and shape of an open pit. These must be properly understood and used in the planning of any open pit operation. The ...

Shaft Mining, Mining Techniques, Underground Mining ...
Shaft Mining. Shaft mining is a form of underground mining where shafts are pushed vertically from top to bottom to excavate the ores and minerals. It is also called shaft sinking. It is best suited for concentrated minerals such as iron, coal, etc. which can be found at the depth of the earth's surface. It is found mostly all over the world.

Longwall Mining Overview | Introduction | underground COAL
LONGWALL MINING Overview. In the method of secondary extraction known as longwall mining a relatively long mining face (typically in the range 100 to 300m but may be longer) is created by driving a roadway at right angles between two roadways that form the sides of the longwall block, with one rib of this new roadway forming the longwall face.

Block Diagram
Block diagrams use very basic geometric shapes: boxes and circles. The principal parts and functions are represented by blocks connected by straight and segmented lines illustrating relationships. When block diagrams are used in electrical engineering, the arrows connecting components represent the direction of signal flow through the system. Whatever any specific block represents should be ...
Block caving: A new mining method arises |
Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight. It is the underground version of open pit mining. In block caving, a large section of rock is undercut, creating an artificial cavern that fills with its own rubble as it collapses. This broken ore falls into a preconstructed series of ...
Crandall Canyon
Diagram detailing the boreholes drilled during the rescue attempt. At the end of August 2007, with all efforts having failed to loe the miners missing in the Crandall Canyon mine for more than three weeks – and presumed dead – the US Department of Labor announced an independent investigation to look into the handling of the disaster. The coal mine is loed in the northwest of Emery ...
