This report is a continuation and expansion of a previous Bureau of Mines grant (No. G0254004) that examined alternative methods of handling the parting between two coal seams in a surface mining operation. The alternative methods consist of equipment implementation in either a stowing or haulback technique. Following a typical strip mine conformation, the parting is directly stowed or hauled back and placed in the pit bottom after second seam removal. The objectives are to produce an environmentally sound material placement technique and to increase prime stripping machine utilization. This two-volume report contains the engineering philosophy behind two computer programs (the production profile program and the equipment capabilities and cost estimating program) created to evaluate parting handling methods over a wide range of coal and parting thickness ratios.
