Use of Gas Mixing Equations and Simulation Approaches in the Design of Mine Inertization Systems


The primary objective of the study is to examine gas mixing and dilution approaches to give a better understanding of how acceptable levels of contaminants within a mine atmosphere can be evaluated. As an example the interaction between gases from inertization systems and the underground mine atmosphere can be evaluated to assist in design of the mine inertization system. Inertization approaches include use of engine exhausts, nitrogen, carbon dioxide, and diesel fired boiler units. Inertization systems for handling underground fires, spontaneous combustion heatings and management of the potential explosibility of newly sealed goafs have been accepted as important safety approaches within the many parts of the international industry. Case studies of the designs and applications of inertization systems to assist in stabilising mine atmosphere situations are given.
