    The surface mining methods are: (i) open pit mining, (ii) drift mining, (iii) slope mining, (iv) contour mining, and (v) auger mining The characteristic that distinguishes open pit mining is the thickness of the coal seam insofar as it is virtually impossible to backfill the immediate mined out area with the original overburden when extremely thick seams of coal are involved19/01/2016· The steel cutting drum was a genuine industrial component; the miner was bronze, cast by John Galizia & Son Ltd, 36 York Road, Battersea, London; the lump of coal was modelled in fibreglass, coloured bronze, as was the spiral screw which formed the base The sculpture was installed at Lowton in July 1965, where it was formally unveiled by Lord RobensThe Miner or The Anderton Mining Monument, St HelensLoad Transfer Characteristics of Plain and Spiral Cable Bolts Tested in New Non Rotating Pull Testing Apparatus, Naj Aziz, Ali Mirza, Jan Nemick, Xuwei Li, Haleh Rasekh, and Goefang Wang PDF Review of Horizontal Surface Movements Due to Longwall Coal Mining Using Numerical Modelling, James Barbato, Bruce Hebblewhite, Rudrajit Mitra, and Kevin Mills PDF SelfCoal Operators Conference Papers and Proceedings – Mining
