Coal mining by the auger method entails boring horizontal or near-horizontal holes in an exposed face of the coal and loading the coal removed by the auger Single dual or triple auger heads can remove up to 90 inches of coal for over 200 feet Augering is used to supplement recovery at contour or strip mines when the overburden becomes too great to be economically removed It

Glossary of Mining Terminology A Abutment — In coal mining (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides which act as abutments of the arch of strata spanning the roadway and (2) the weight of the rocks over a longwall face is transferred to the front abutment that is the solid coal ahead of the face and the back

Surface auger mining at Rietspruit Mine Services (Pty) Ltd by M J Lukhele* Paper written on project work carried out in partial fulfilment of B Tech (Mining Engineering) degree Synopsis A number of high wall mining methods were developed over the years to mine coal reserves exposed on the high walls created during surface mining The auger mining system was

Mining is the extraction of valuable minerals or other geological materials from the Earth usually from an ore body lode vein seam reef or placer deposit These deposits form a mineralized package that is of economic interest to the miner Ores recovered by mining include metals coal oil shale gemstones limestone chalk dimension stone rock salt potash gravel and clay

Definition of auger mining

A mining method often used by strip-mine operators where the overburden is too thick to be removed economically Large-diameter spaced holes are drilled up to 200 ft (61 m) into the coalbed by an auger Like a bit used for boring holes in wood this consists of a cutting head with screwlike extensions As the auger turns the head breaks the coal and the screw carries it
