The Use of 3D Simulation System in Mine Ventilation Management
Procedia Engineering, 2011 The Donghai mine has been mined to -1000 meters, three mining areas share one return shaft, some laneway resistance values are very large, and fan air pressure reach more than 3500pa. The ventilation system is complex and difficult to manage.

Ventilation is a vital component of an underground mining operation, used to guarantee a safe atmosphere for workers and survive them from the hazardous and toxic gases. In the recent years, engineers have begun to apply new operation research techniques in order to optimize the ventilation systems to assist in achieving a regulatory compliance, reduce

Modelling of heat flow in underground coal mines using Ventsim [PDF]
Heat in underground coal mines can pose a significant problem, especially in the hot climate of Central Queensland. At the moment, little planning is done before mining commences to try and limit the problem. There are temperature predicting tools on the market, but many of those are either difficult to use by themselves, or difficult to integrate into

Re-entry into blast fume affected underground areas is a safety and productivity concern for most mines. Overestimation of the re-entry time may improve clearance of noxious gases but can result in production delays and decrease overall productivity while underestimation of the re-entry time will also lead to safety and health problems.
