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.

WebIf the graph is d-regular, then L= Id A hence i = d i Note that if it is not regular, then we do not see this relationship immediately. So the largest eigenvalue of the adjacency matrix of a d-regular graph is dbecause we know the smallest eigenvalue of the Laplacian is 0. The eigenvector is the uniform eigenvector. 4.3 Non-regular graphs
