Western Yunnan Copper Mining Difficult Ventilation System Optimization And Stope Ventilation Simulation

Collection optimization of the ventilation system must be the basis of data, analyze it, organize, summarize, and in accordance with the Merry control technology at home and abroad and a copper mine production conditions, intended use of multi-level stations in series, parallel operation mode romantic sport regulation and control program, a copper mine ventilation system optimization research.Overall consideration stations at all levels responsible for the transport of air flow, ventilation resistance to be overcome along the way, the fan model selected stations at all levels; solver software application ventilation network computer program of the proposed multi-level stations on the air distribution, loss of air pressure, power consumption and other parameters to understand the operator analysis, the optimum reform scheme of the mine’s ventilation system, the program can effectively solve the mine ventilation system required air flow is not enough, because there is no ventilation system environment formed in the mine will be able to go up and down, suddenly big suddenly small natural romantic problems; under the lower part of the mining plan, study and propose appropriate ventilation system construction plan, when transferred to the deep mining, just a minor adjustment according to the actual situation continue to play a role, to meet the production needs of the long-term; Fluent stope ventilation were simulated and analyzed, the venue of the flow field of distribution in the case of selected auxiliary fans of the stope conditions point to simulate mining; established a set more comprehensive, science, in line with the actual mine ventilation system solutions to optimize the index system, ventilation system evaluation model based on BP neural network test proved the feasibility of the model.The innovation of this paper is to Fluent software used in ventilation simulation, stope ventilation simulation, analysis stope the romantic market conditions, the simulated results with optimal results complement each other, mutual authentication.
