Feasibility of draglines for mine reclamation
Draglines are presented in this paper as an alternative for mine reclamation in steep sloping areas. The paper includes a history of draglines. Early development is summarized, and major improvements are discussed. Unreclaimed acreage in Kentucky and the mining and reclamation methods traditionally used for strip mines in Kentucky are discussed. The engineering feasibility of draglines is discussed. Bearing capacity and slope stability are presented as factors which influence the engineering feasibility of draglines in steep sloping areas. A presumptive value of bearing capacity for a typical spoil bank is calculated. The factor of safety against slope stability failure is discussed. A reclamation method which minimizes the risk of bearing or slope stability failures is presented. The economic feasibility of cost and production costs of dragline equipment is compared to the initial cost and production costs of other reclamation equipment. In addition, the Crescent scraper system is introduced as an alternative to conventional dragline bucket and line systems. 11 references, 8 figures, 1 table.
