SIMULATION ON THE CLOSURE OF JIET VENTILATION STATION PERFORMED WITH 3D CANVENT

Marius-Simion Morar

Abstract

For underground extraction of coal are running a complex network mining vertical, horizontal and inclined role extraction, transportation and evacuation on the surface. Associated system of mining works has the ventilation network to ensure the oxygen necessary for workers, diluting explosive gases and toxic substances and evacuated heat and humidity from the underground. For air evacuation from the underground workings, from the point of entry of fresh air to the polluted air exit point, is used powerful fans located on the surface in the main stations. 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. Simulation in the ventilation system requires a thorough analysis of the ventilation network, involves processing a large amount of data, and it's needed using IT equipment and specialized software. To simulate the closure of the Jiet ventilation station I used the 3D Canvent software. The paper presents simulation on the closure Jiet ventilation station from the Lonea mining unit, as well resolving of the ventilation network after closing.
