Study of Application of Optimal Reconstruction of Mine Ventilation System by Mine Ventilation Simulation System MVSS

摘要

To solve the ventilation problems of Jinchuan Group Ltd, mine ventilation simulation system is constructed and developed by using ventilation network theory, graph theory, set theory. The functions and optimal adjustment mathematical model of Mine Ventilation Simulation System (MVSS) are discussed, and MVSS is used to simulate the influences of the increase or decrease of roadways on the surrounding other roadways and to simulate the influences of the backouts or installations of fan stations on the surrounding ventilation system. The method of determining optimization and reconstruction schemes by using MVSS is illustrated with the example of 1 150 level of Jinchuan mine, which provides a scientific tool for the analysis of ventilation system actuality, ventilation network optimums and ventilation designs.
