Study Of Ventilation System Optimization Alteration Based On Simulation Technology For Chensilou Coal Mine

The ventilation system is one of the major systems of the coal production. The basic guarantee for mine safety production is to construct and complete mine ventilation system. The optimization of ventilation system reform is an important part of the mine optimization. It plays an important role to create a good working environment in the mine, to protect the health and labor safety of underground workers, to prevent all kinds of mine disasters. The optimization of mine ventilation system is one of the important means to protect the mine safety and efficient production. In this thesis, the research projects of 《The development and application of Chensilou Coal Mine ventilation simulation system》 is as the background. It is completed by closely integrated field practice. The existing ventilation system is analysed, and Mine ventilation simulation system is used to construct Chensilou coal mine ventilation simulation system. For Chensilou coal mine ventilation system, MVSS is used to achieve no initial value of iterative solution and ventilation network on-demand air distribution under the fixed semi-cut set. MVSS is used to conduct optimum and adjustment for mine ventilation system by node method. Simulation analysis was carried out on the adjustment scheme of ventilation system. According to the results, the ventilation system adjustment in different stages is smoothly realized.As the thesis completed, for Chensilou coal mine management of ventilation systems, it provides new methods and management concepts to support for the management and improvement of ventilation systems.
