矿井通风系统网络解算与通风状态模拟

Mine ventilation network calculation and ventilation simulation

为预测某矿拟新建风井进行通风系统改造的效果,按照煤矿安全规程要求,在改造前对矿井的通风阻力进行了测定,计算出井下各巷道的摩擦阻力系数,在此基础上建立了矿井通风系统解算模型,并采用风丸矿井通风解算软件对新风井投用前后的矿井通风状态进行解算模拟。结果表明,新风井投用后该矿矿井通风系统得到有效改善,能够降低矿井通风阻力,增加有效风量,实现分区通风,为矿井顺利进行通风系统改造和风量调整提供了科学依据。

In order to predict the improvement effect of newair shaft in the plan, according to the requirement of safe mining regulation, ventilation resistance was measured before improvement, frictional resistance coefficient of every roadway was calculated, calculating model for mine ventilation system was set up, the ventilation effect of the new air shaft before and after improvement was simulated by Fengwan mining calculation model ventilation system. The result showed that the improvement will perfect the mine ventilation system, reduce ventilation resistance, increase effective air volume, realized zoned ventilation and provide scientific data for the improvement of ventilation system and air volume adjustment.
