UPDATING THE LONEA MINE VENTILATION NETWORK USING THE VENTSIM VISUAL ADVANCED PROGRAM
Abstract
The ventilation network related to a mining unit for the exploitation of the useful mineral substance aims to ensure optimal microclimate conditions in underground. An ventilation network is made up of nodes and branches in order to establish its structure. In this sense, the mine ventilation must be seen as a source of life, in which the ramifications represent at the same time the arteries that transport the air to the working fronts and the evacuation of the poluted air to the surface. In order to establish the optimal air flows at the level of ventilation networks, specialized programs are used with the help of which it is possible to model, solve and optimize them. The solution or calculation of the ventilation system consists in establishing the quantitative distribution of air flow, in terms of network elements and the characteristics of depression sources. The Ventsim Visual Advanced program was developed to respond to the requirements regarding the simulation and design of underground environmental conditions, to ensure adequate conditions for miners and equipment. Primarily, it was designed as a ventilation tool, which can work independently of other mine planning software, but ensures a high level of compatibility. The analysis carried out on the ventilation network of the Lonea mine leads to the conclusion that the ventilation network of the mine is particularly complex, complexity amplified by the large number of ventilation constructions. In the framework of this work, the update of the ventilation network of the Lonea mine will be treated with the help of the Ventsim Visual Advanced program.
