某铜矿通风系统优化模拟

Optimization and simulation of ventilation system in a copper mine

某铁矿在其Ⅴ矿体下盘伴生数个铜矿体,采用分段空场嗣后充填法回采,原有开拓系统未形成完整的通风系统。计划将铜矿改造成独立的回风系统,以确保铜矿回采的需风量和通风效果。在对原通风系统进行分析的基础上,首先进行了矿井需风量计算,并对拟采用的新通风系统进行优化;建立了包含巷道断面尺寸、长度、巷道位置、风机型号、风机参数性能及机站位置等参数的数据库,将数据库的数据导入计算机进行解算,得到解算结果。

Several copper bodies are associated with its V ore-body footwall in an iron mine, The stoping method taken is the sublevel open slope filling method. The existing ventilation system is not complete. It intends to improve the copper mine by building a separate air return system to ensure its require airflow and ventilation effect. On the basis of analysis of the existing ventilation system, required airflow for the mine shaft is calculated and the proposed new ventilation system is optimized. A data-base containing cross-section size, length and location of road- way, model and parameter performance of fan, station location and other parameters is set up to input data in the database into computer for decoding and calculating results.
