Application of VENTSIM 3D and mathematical programming to optimize underground mine ventilation network: A case study
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 ventilation costs, and improve its efficie...
متن کاملDegree-layer theory of network topology
The network topology can be described by the number of nodes and the interconnections among them. The degree of a node in a network is the number of connections it has to other nodes and the degree distribution is the probability distribution of these degrees over the whole network. Therefore, the degree is very important structural parameter of network topology. However, given the number of no...
متن کاملA Brief History of Mine Ventilation
Observations of the movements of air in underground passages have a long and fascinating history. Between 4000 and 1200 BC, European miners dug tunnels into chalk deposits searching for flint. Archaeological investigations at Grimes Graves in the south of England have shown that these early flint miners built brushwood fires at the working faces—presumably to weaken the rock. However, those Neo...

متن کاملDevelopment of an expert system for on-line ventilation network analysis and graphic representation of mine ventilation parameters
The importance of ventilation analysis has increased in recent years as a means to determine the optimum ventilation design. The problem of ventilation is quite complicated due to a number of factors, such as increasing length and other complexities of airways, and difficult geological conditions. Therefore, it has been strongly felt that an intelligent ventilation analysis system, which could ...
