Risk estimation approach considering implementation of automated ventilation systems into kazakhstan metal mines

Abstract

With shifting from traditional to automated ventilation system it is necessary to estimate technical and financial risks which might influence on mining currently use in Kazakhstan. This requires development of a new approach to estimate technical applicability and financial viability of implementation of automated ventilation systems into operational metal mines. Methodology use estimation of propagation of uncertainty sources through an operational risk framework that considers impacts on the existing mine ventilation system and automated ventilation benefits based on estimation of Net Present Value (NPV). Developed approach is considering risks of investment into reconstruction of the mine ventilation network that can be suitable for implementation of automated ventilation systems. The approach is also estimate risks and opportunities related with financial optimisation of ventilation network designed on outdated local regulations and on modern regulations. The approach can contribute to decision making on acceptance of global practices for mine ventilation design in Kazakhstan considering potential economical profit based on optimisation by implementation of automated ventilation. Results of this study will help to estimate ventilation efficiency in agreement with underground mine safety regulations and might assist Kazakhstan change the outdated regulations for the better.
