Underspoil haulage is defined as the transport of coal from the pit bottom by conveyor through a tunnel maintained under the spoil piles. The main objective in promoting this study was to test, through engineering and economic analysis, the feasibility of constructing and operating this belt conveyor underspoil haulage system. Other continuous coal transporting concepts were also to be proposed to supplement underspoil haulage systems and to provide technical and economic comparisons to underspoil systems. Four underspoil haulage systems for underspoil haulage of coal from a model strip mine were investigated and compared to more conventional truck haulage. Underspoil haulage showed itself to be economically favorable for coal thicknesses greater than 40 feet buried under 100 feet or more of overburden and mined at five million tons or more per year. Secondary studies showed that several other continuous haulage methods are potential as alternatives to underspoil haulage or may be operable under criteria that are impractical for underspoil.
