Abstract
Because of their limited dumping radius, present stripping draglines will not be as effective in mining the deeper overburden depths and thick seams in western coal deposits. These casting limitations of the dragline at depths have led to the selection of shovels and haul trucks for the removal of overburden by a substantial number of western operators. The deeper surface coal mines in Europe have developed bridge conveying systems for handling spoil, and similar approaches appear to be applicable in western U.S. coal deposits. Examination of the concepts and preliminary design work of four equipment systems produced by contractors for the federal Bureau of Mines supports the potential development of a mobile overburden conveying system capable of operating in conjunction with present U.S. excavating machines.
