The Large Open Pit (LOP) has been sponsoring a research project on updating the guidelines for open pit slope Design Acceptance Criteria (DAC) – see here for detail. As part of this update, a summary of leading practice and target criteria for bench scale design and reconciliation are being drafted, which will be included with the final LOP update document. To ensure that the criteria in the document reflect industry’s leading practice, we have redeveloped a very brief questionnaire to gather industry’s practice. We invite geotechnical leads from different operations and experienced consultants to participate by contacting Dr Renato Macciotta (macciott@ualberta.ca) to get a copy of the survey. All responses will be kept confidential and only anonymized, aggregated results will be shared with the LOP reviewers for evaluation.
