•Coal deposits are mined by cutting a network of 'roads' into the coal seam & leaving behind 'pillars' of coal to support the roof of the mine. •These pillars can be up to 40% of the total coal in the seam – although this coal can sometimes be recovered at a later stage by 'retreat mining'.The roof is then allowed to collapse and the mine is
There are localized transport systems at the mining face areas to carry the coal from the cutting machines to the main transport systems. These localized transport systems (shuttle cars AFC s BSL s etc) are dealt with in following sections relative to the different types of mining. This section refers to the main transport systems out of the

To benefit from such technology, the Bureau is investigating remote, computer-assisted operation of mining systems for underground, highwall, and surface mining applications. A cornerstone for computer-assisted operation is an effective guidance system.
Highwall — The unexcavated face of exposed overburden and coal in a surface mine or in a face or bank on the uphill side of a contour mine excavation. Highwall miner — A highwall mining system consists of a remotely controlled continuous miner which extracts coal and conveys it via augers, belt or chain conveyors to the outside.
Glossary of Mining Terms - Coal Education. 2018-1-4 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 ...
Production from surface mines is crushed for railroad car loading and direct shipment to customers without coal preparation. All underground mine and highwall mining production will be washed at the Kopper Glo coal preparation facilities. Coal is transported to the coal preparation plant and load-out facilities by coal trucks and conveyor belts.
