摘　　要：从矿井通风安全在线分析的动态特征入手,提出了在线分析面临的基础数据偏差及在线分析精度问题。分析了日常通风基础数据的偏差问题,指出了通风基础数据偏差主要影响因素和特点;在阻力数据分析的基础上提出了通风安全分析的精度的问题,将分析精度分为静态精度和动态精度2种。分析提出,要保障通风安全分析的静态精度,需要以通风阻力测定为基础,要保障通风安全分析的动态精度,需要从动态监测的数据维度和精度2方面进行保障,数据维度方面包括时间维度和空间维度2种。From the start of dynamic characteristics of on-line analysis of mine ventilation safety, the basic data bias and on-line analysis accuracy problems of online analysis was proposed in this paper. Firstly, the problem of deviation of daily ventilation basic data was analyzed and the main influencing factors and characteristics of data deviation of ventilation basic data were pointed out. Based on the analysis of resistance data, the accuracy of ventilation safety analysis was proposed and the analysis accuracy was divided into static accuracy and dynamic accuracy. The analysis proposed that the measurement of ventilation resistance can ensure the static accuracy of ventilation safety analysis. The dynamic accuracy assurance of ventilation safety analysis was based on dynamic monitoring of data dimension and accuracy. The data dimensions included time dimension and spatial dimension.
