Validation and Stress-testing of the proposed Design Acceptance Criteria (DAC) matrix for open pit mining

Open pit slope engineering involves balancing economic requirements and risk, where an optimum pit slope design seeks to safely increase the slope angles to minimize the mining of waste, while maximizing ore recovery. In turn, this can reduce the carbon footprint of the operation, as less excavation is required. An optimum slope design must satisfy Design Acceptance Criteria (DAC) considering the uncertainties in the input parameters and the potential consequences of slope failure. Addressing these requirements has motivated the development of a proposed DAC reliability-risk based matrix for open pit mining, which requires validation. This project will validate a proposed DAC matrix in the basis of a robust mathematical and empirical base; as well as against published practice and society’s tolerance across different industries, and their perceived risks and benefits. The outcome will help the economic and environmental sustainability of this important activity in Alberta, and Canada overall.
