Healthy and safe working conditions underground, especially in areas with potentially explosive atmospheres depend mainly on the method of operation and management of the ventilation system.
For underground extraction of coal are running a complex network mining vertical, horizontal and inclined role extraction, transportation and evacuation the surface.
Associated system of mining works has the air network to ensure the oxygen necessary for workers, diluting explosive gases and toxic substances and preparations to evacuate heat and humidity in the underground. For air evacuation in the underground workings active route, from the point of entry of fresh air to the polluted air exit point, using powerful fans located on the surface in the main stations.
The mining ventilation is a domain extremely sensitive and complex that encompasses many disciplines in the service of achieving and maintaining security conditions underground.
Improving the management of the ventilation system requires a thorough ventilation network analysis, that a large amount of data to be processed using IT equipment and specialized software.
This paper presents an analysis of the expansion of the network Lonea mining unit and resolving network in perspective ventilation using 3D Canvent software.
