This report documents a project to develop a cross pit conveyor system for the Bureau of Mines. The conveyor system description includes details of the conceptual design as well as system and component specifications. The selection of primary and backup sites for system demonstration is discussed. Maneuvers and operating sequences required for mining the selected demonstration site are described and illustrated. Economic viability of the system was analyzed by estimating the cost of overburden removal per ton of coal using the Battelle-designed concept and comparing these costs with the cost of a state-of-the-art 30-yd3 dragline operation. Testing and trade-off studies conducted are documented and the results presented. Alternate designs considered in developing the selected concept are included. Based on the evaluation of the selected concept, it was concluded that the cross pit conveyor system proposed by Battelle is a technically and economically feasible overburden handling method with a good potential to improve western coal mining efficiency.
