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. WebEl método gráfico de estabilidad fue inicialmente propuesto por Mathews (1981) y. subsecuentemente modificado por Potvin (1988) y Nickson (1992) para posteriormente. …

Web11 mrt. 2024 · Stability Eigenvalues can be used to determine whether a fixed point (also known as an equilibrium point) is stable or unstable. A stable fixed point is such that a system can be initially disturbed around its fixed point yet eventually return to its original location and remain there. A fixed point is unstable if it is not stable. Web6 jul. 2024 · Abstract The Mathews method of predicting open-stope stability was first proposed in 1980.
