DRAGLINE APPLICATIONS

[Div Bar Image]

Mine Engineers, Inc. has developed detailed mine plans, equipment schedules, sequences, productivity, costs, and other specific items on several difference dragline operations and proposed operations. Types of operations range from single seam side cast stripping to multiple thick and thin seam stripping utilizing extended bench, two pass, spoil side, cast blasting, and other techniques to complete overburden and interburden removal. Applications engineering work has also included review of existing operations and development of modifications for improved productivity. Representative projects include the following:
