本文以因次分析法为基础,建立矿井通风系统的因次方程式,根据π定理,求得描述矿井通风系统优劣的五个无因次数,它们即为通风系统基本鉴定指标。这种方法不同于传统的根据经验和需要编制鉴定指标的方法。 通过推理和分析,建立了一种形式较为合理的综合指标。并用建立的鉴定指标,对国内某些冶金矿山通风系统进行了评述。
Based on the factor analysis method, this paper establishes the factorial equation of mine ventilation system. According to the π theorem, five dimensionless numbers describing the advantages and disadvantages of the mine ventilation system are obtained, which are the basic identification indexes of the ventilation system. This method is different from the traditional method of preparing accreditation indicators based on experience and needs. Through reasoning and analysis, a more comprehensive form of indicators is established. And with the establishment of identification indicators, some domestic metallurgical mine ventilation system were reviewed.
