柿竹园多金属采矿场矿井通风系统优化研究

Research on Optimization of Mine Ventilation System in Shizhuyuan Polymetallic Mining Field

本次通风系统的优化范围为柿竹园多金属采矿场+368 m与+586 m之间的通风系统。根据现场调查发现实际存在的问题,并结合多金属采矿场未来的通风需求,从通风网络、通风动力、通风构筑物三个方面对井下通风系统进行优化。监测数据表明:优化方案明显改善了井下通风质量,解决了井下新风短路、污风串联,漏风严重、东部北部排风困难等问题,以及合理利用自然风压。

The optimization scope of the ventilation system this time is the ventilation system between+368 m and+586 m in the Shizhuyuan polymetallic mining field.Based on the actual problems found in the on-site investigation,combined with the future ventilation needs of the polymetallic mining filed,the underground ventilation system is optimized from three aspects:ventilation network,ventilation power,and ventilation structures.Monitoring data show that the optimization scheme has significantly improved the quality of underground ventilation,solved the problems of short-circuit of underground fresh air,series connection of polluted air,serious air leakage,and difficulty in exhausting air in the northeast,and rational use of natural wind pressure.
