摘要
基于矿井通风系统阻力测定基本理论,简要分析了矿井通风系统阻力测定方法和测定的准备工作,并对矿井通风系统阻力测定的相对误差及其主要影响因素进行了分析,指出相对误差影响因子包括计算阻力和实测阻力两部分,在保障测试和计算准确的前提下,相对误差可以限制在5%以内,测试结果可用。
Based on the basic theory of the resistance measurement of mine ventilation system, this paper gave a brief description of the resistance measuring method for mine ventilation system and the preparation of the measurement, analyzed the relative error and its influence factors of the mine ventilation system, and pointed out that the influence factors of the relative error should include the calculated resistance and the measured resistance, and on the premise of accurate testing and calculation, the relative error can be limited within 5%, the test results are available.
