摘要
矿井通风系统存在风阻较大的问题,造成井内负压较大,严重影响井内生产安全与生产效率.通过明确通风系统风阻测定的方法与测算方式,掌握风阻影响因素,可以对通风系统进行优化设计,达到降阻减压的目的.优化设计主要包括3个方面,即通过自然分风减小功耗、调节主通风机频率和增加回风措施井.最后进行仿真应用效果分析,结果表明,优化后的矿井总风阻减小350.57 Pa,负压减小440 Pa,降阻减压效果明显.
Abstract
There is a problem of high wind resistance in the mine ventilation system,which leads to a high negative pressure inside the mine,seriously affecting production safety and efficiency.By clarifying the methods and calculation methods for measuring wind resistance in ventilation systems,mastering the factors affecting wind resistance,the ventilation system can be optimized and designed to achieve the goal of reducing resistance and pressure.The optimization design mainly includes three aspects,namely reducing power consumption through natural ventilation,adjusting the frequency of the main ventilation fan,and adding return air measure shafts.Finally,simulation application effect analysis was conducted,and the results showed that the optimized mine total wind resistance decreased by 350.57 Pa,negative pressure decreased by 440 Pa,and the resistance and pressure reduction effect was significant.
