Mining consists of two operations Removing Overburden(OB) followed by Mining out Coal. To reach the coal we need to remove high amounts of OB which depends on the surface topography and geology of area in which mining is being carried out. This...
Stripping Overburden Line Mining Us nige Wark. Stripping Overburden Line Mining. FOB Reference Price: Get Latest Price In mining stripping ratio or strip ratio refers to the ratio of the volume of overburden or waste material required to be handled in order to extract some tonnage of oreFor example a 3 1 stripping ratio means that mining one tonne of ore will require mining three tonnes of
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a ''pit'', and
Coal mining has been performed since the arrival of the Industrial Revolution in the mid18th century. Coal is used as a fuel primarily for steamgenerated electrical power plants, as well as being a component of certain industrial applications, such as steel manufacturing.
A power machine shaves the coal along the face over the entire length of a panel designated for mining. Selfadvancing hydraulic lifts are used to hold the ceiling in place until mining is completed on a given panel. The lifts are then removed and the ground is permitted to subside.
In addition to top soil and rock, the overburden is caused by general coal mining operations, a waste product consisting of coarse rock fragments and fine coal particles. Montecarlo Construction is using a fleet of Constriction Equipment ( CE) machines, including five EC480 DSeries and three EC700 BSeries crawler excavators, as well as 41 onhighway tipper trucks, to move

quot;Strip miningquot; is the practice of mining a seam of mineral, by first removing a long strip of overlying soil and rock (the overburden); this activity is also referred to as quot;overburden removalquot;.It is most commonly used to mine coal and lignite (brown coal).Strip mining is only practical when the ore body to be excavated is relatively near the surface.
Dragline A large excavation machine used in surface mining to remove overburden (layers of rock and soil) covering a coal seam. The dragline casts a wire ropehung bucket a considerable distance, collects the dug material by pulling the bucket toward itself on the ground with a second wire rope (or chain), elevates the bucket, and dumps the material on a spoil bank, in a hopper, or on a pile.

Pictured here in 1961 is a Marion walking dragline removing overburden at a coal surface mining operation near Estevan, Saskatchewan. As can been seen in the photo, the Great West Coal Company needed to remove a large amount of material to access the high quality coal seam, and the ideal method was with a large dragline.

#0183;#32;The present invention relates to a system and a method for removing overburden from a valuable mineral deposit such as a coal seam. In strip type open cut coal mines such as those in the Bowen Basin of Queensland and other regions of the world, draglines are widely used and are a very cost effective means of removing the overburden above seams of coal for depths up to about 50
Overburden removal can begin after topsoil and subsoil have been removed. In areas of thick overburden, a hydraulic excavator and a fleet of end dump trucks are used to remove part of the overburden prior to dragline operations. The excavator and truck overburden removal step was introduced into BNIs mining process in 2012.
