Risk Analysis for Rock Slopes in Open Pit Mines. Part IV. Field Exploration to Determine Rock Mass Properties

H. H. Einstein / G. B. Baecher / D. Veneziano / H. C. Chan / W. S. Dershowitz

Sampling plans and methods of statistical inference for rock mass properties are developed aimed at overcoming statistical biases in drawing inferences from joint survey data. The approach to exploration strategy analysis (optimization) is through the 'expected value of information' (EVI) of decision theory and two cases are analyzed: the one-joint set (parallel to slope) case and the general shear case. In conjunction with the analysis of optimal exploration strategies for single slopes, a graphical risk screening procedure was developed to determine those slope sections within a pit for which increased exploration would beneficially reduce risk.
