WebThe technique to use will be the Mathews Stability Graph Method that allows to evaluate by two input parameters, Stability Number (N ) and Hydraulic Radius (RH), whether the proposed design is in a stable area or not. N is a factor associated with the rock mass, constant value, and the RH is a variable related to the stope dimensions. Web8 nov. 2014 · Synopsis The Mathews method of predicting open-stope stability was first proposed in 1980. The initial stability graph was based on a limited number of case studies, prim- arily from deep, North American, steeply dipping open stopes in strong rocks of medium to good quality.
