Application of microcomputers in surface coal mine design

Surface coal mine design has traditionally relied on graphic and analytic approaches for pit layout and equipment selection. A number of interactive graphic microcomputer programs have been written that aid in the design process in the academic arena and should also have industrial applications. The programs described include a drag-line cut diagram and production index calculation program, a downslope load scraper cut diagram and volume program, and an overburden volume and coal tonnage sequencing program.
