摘要:

三鑫金铜矿原采用多级机站通风,随着生产中段下延及增多,存在矿井总风量不足、风机运行效率低、部分中段风流反风及通风困难等问题。通过对总需风量进行校核,有针对性地提出了3种通风系统优化方案,利用Ventsim三维动态仿真模拟软件解算和定量定性分析比较,选择了前期井下集中+后期多级机站接力的通风系统方案。按照优选方案组织改造实施后,经过通风测定,总风量、进回风风速都达到了设计要求,有效风量率达81.33 %,主扇运行效率达85 %以上,处于高效率区运行,通风效果明显改善。

Abstract:

The previously adopted multi-level station ventilation of Sanxin Gold-Copper Mine encounters insufficient overall shaft air flow,inefficient fan operation,backflow and bad ventilation in certain levels with downward extension and increasing numbers of operation levels.Based on checking of overall airflow demand,the study correspondingly put forward 3 ventilation system optimization plans.By quantitative and qualitative analysis and comparison and calculation with Ventsim 3D dynamic simulation software,the ventilation plan of underground centralization in earlier stage+multi-level station relay in late stage is selected.With the implementation of the optimized selection plan,the overall airflow and the air flow rate of inflow and outflow all meet the design requirement according to ventilation verification.The effective airflow rate reaches 81.33 %.The main fan operation efficiency reaches over 85 %,running in high efficiency range.The ventilation is notably improved.
