Mining is a very heavy industry. Every day miners take incredible risks to extract valuable ores and minerals from the earth's crust. In order to ensure the safe operation of the underground, adequate ventilation is required to ensure that the workplaces are permanently supplied with fresh air. By combining general ventilation with kilometers of secondary ventilation specific ventilation pipes, mining ventilation is a special area where errors can occur.
Modeling and simulation of mining ventilation networks have become widespread in the mining industry. There are a number of computer programs for analyzing mining ventilation networks that are currently used to design, analyze and operate ventilation systems. Most of these programs have a graphical representation of the ventilation network and the related quantities, such as air losses in the branches, fan characteristics, heat transfer calculation, natural ventilation, etc. In addition, most of them include gas motion simulation, as well as simulations for altered conditions, such as fire cases, although these are usually stable models. This paper presents the analysis and solving of a complex ventilation network, the analysis of the gas dispersion dynamics under normal conditions of ventilation network structure and the dispersion of methane, carbon dioxide and carbon monoxide under normal conditions. |
