基于Ventsim Visual^TM高海拔矿井按需通风热模拟研究

Study on Thermal Environment Simulation of Ventilation on Demand of High Altitude Mine Based on Ventsim Visual^TM

高海拔高寒环境下,为保证井下生产安全和提高生产效率,矿山主要采用电预热等传统预热方式,不仅能源价格高昂,同时还面临着运输不便等难题。某铜矿属于典型的高海拔矿山,为克服传统预热的弊端,研究按需通风与回风余热回收技术,利用Ventsim Visual^TM三维通风仿真系统进行井下热环境模拟研究,预测某铜矿全负荷、正常负荷、一般负荷以及轻负荷工况条件下按需通风的回风热力学参数,证明矿山采用回风余热回收技术的可行性和节能前景。

In the high altitude and alpine environment,in order to ensure the safety of underground production and improve efficiency,traditional preheating methods such as electric preheating were adopted mainly in mines,which faced the disadvantages in high price and transportation.A copper mine was a typical high altitude mine,in order to overcome the disadvantages of traditional preheating,the technology of ventilation on demand and waste heat recovery of return air was studied,the Ventsim Visual^TM 3D ventilation simulation system was used to simulate the underground thermal environment,and the thermodynamic parameters of return air for ventilation on demand of full load,normal load,general load and light load were predicted,which proved the feasibility and energy saving prospect of adopting the technology of waste heat recovery of return air in the mine.
