The Consolidated Mathews Stability Graph for Open Stope Design

The stability graph method for open stope design is one of the most widely used approaches predicting stopes in underground metalliferous mines. primary purpose this work to propose a new chart, which includes all relevant case histories, and exclude parameters with uncertainties determining number. modified number was achieve goal, Extended Mathews database recalculated compared graph. In study, refined Consolidated developed by excluding entry mining methods data from data, only non-entry used. applicability proposed chart demonstrated an example. probabilities each surface were determined using logistic regression model chart. Comparing analysis results that other published works same example shows entry-method excluded, produces more conservative safer design. conclusion, size quality dataset dictate reliability approach.
