A Study Of Mesh Ordering Techniques For Mine Ventilation Network Solution Methods

A number of solution methods for solving the nonlinear equations derived from mine ventilation networks use meshes selected from the network as the basis of the solution techniques. Mathematicians working in network theory have outlined several methods for speeding up the computations through mesh selection and ordering procedures. In the mine ventilation area, a fair amount of attention has been paid by ventilation specialists to procedures for choosing the meshes so that the computational effort is eased. However, little attention has been paid to mesh ordering methods. This paper outlines research into random mesh ordering procedures plus two non-random mesh ordering procedures and compares some results using these procedures within four solution algorithms.
