World Coal - January 2009
On this month's cover: For coal and oil sand operations that require the removal of large volumes of overburden, P&H Mining Equipment is preparing a new mobile mining crusher (MMC) system, matched to P&H electric shovels, as a cost-effi cient alternative to shovel-truck overburden removal operations. With an eventual return to sustained increased demand and higher costs for diesel fuel, tyres and inherent ancillary road preparation, truck operation and maintenance costs, several high-production, low-cost coal mining operations worldwide see in-pit crushing and conveying systems as a feasible and attractive way to remove overburden.
