| Abstract: |
| Mine ventilation system is united with the underground operating points, it has a global impact on the ventilation safety status of the whole mine, and the optimization of the mine ventilation system has long been an important problem faced by the deep underground mining.In order to solve a large underground deep mining copper mine production process exists in the ore body short strike, large dip angle, multi-level mining at the same time lead to mining area working face dispersion, ventilation system wind road complex problems.The three-dimensional ventilation system simulation model of the mine is established by using Ventsim software. Based on the air demand of the mine, the optimization scheme of the ventilation system for the third, fourth and fifth mining areas is proposed. The simultaneous mining of the nine most unfavorable middle sections of ventilation between-300 m and-700 m is simulated, and the ventilation system network is solved.The results show that the total air volume under the most unfavorable ventilation conditions of the mine is 405.3m3/s, which meets the calculated air requirement of 395.5m3/s for the mine. The research results have important reference value for the safe and efficient production of the mine and improving the economic benefits of the mine. |
