矿井通风系统运行状态模拟及优化控制研究

Study on operation state simulation and optimal control of mine ventilation system

为确定一种安全可靠、运行稳定、通风经济、抗灾能力强的通风系统技术改造优化方案,通过对白坪煤业通风风速较高、中央风井通风系统的通风阻力增长过快、偏高的问题原因分析基础上,采用通风网络解算模拟对通风运行方案进行模拟,根据方案二的模拟结果分析:实施扩巷降阻、及时修复巷道、增加并联风路、缩短风路长度等措施可以保证全井通风系统安全、稳定运行。

In order to determine a safe and stable operation,economy and disaster ability of the ventilation ventilation system technical reconstruction optimization scheme,based on the Baiping mining ventilation,high central shaft ventilation system of mine ventilation resistance is growing too fast,the problem of high reason on the basis of the analysis,using the ventilation network calculation simulation of the ventilation operation scheme according to the results of simulation analysis,the simulation scheme two:implementation of expanded Lane resistance reducing,repairing roadway,timely increase parallel Fan Road,shorten the wind path length and other measures can ensure the safe and stable operation of mine ventilation system.
