COAL MINING TECHNOLOGY - e-library WCL

•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
