User's guide for INSLOPE3: a computer code to analyze the effect of haulage truck operation on dump point stability.
Minneapolis, MN: U.S. Department of the Interior, Bureau of Mines, IC 9291, 1991 Jan; :1-20
Operating mine haulage trucks near the crest of stockpiles and waste dumps is a potentially hazardous practice, often resulting in localized slope failures and dump point accidents. The U.S. Bureau of Mines has developed a computer code (INSLOPE3) based on the kinematic method of limit analysis, which determines an admissible truck weight (upper bound value) for varying distances from the slope edge. The program considers the material strength parameters, slope geometry, and inertial forces induced by vehicle braking. The program can be utilized to assist in the determination of safe operating distances for a haulage truck from a slope edge, the development of safe vehicle operating procedures, and the admissible weight for a static concentrated loading near the crest of an otherwise stable slope. This report provides information on the use of INSLOPE3, interpretation of the results for mining applications, and instructions for acquiring a copy of the software.
