Fording Coal Ltd. is now in its fifth year of a 15-year contract to supply S million long tons of clean coal per annum to its Japanese steel-making customers. The mine employs both conventional truck-shovel and unconventional "walking" dragline coal mining techniques in multiple-seam pits.
This paper describes the present and future application of the 60-cu.-yd dragline and truck-shovel pre-strip-ping fleet in recovering 5- to 40-foot-thick coal seams in mountainous terrain. Deep blastholes, coal flow demands, spring "run-off", seam and inter-seam thrust faulting, limited seam outcrop data and regional faulting are a few of the problems encountered in this application. The author discusses these problems and their solutions as applied at Fording Coal Ltd.
