Abstract
In order to efficiently analyze influence factors of ventilation system and realize the accurate and reliable evaluation, applied principal components analysis to establish mine ventilation system evaluation mode. Based on the principal components analysis of the evaluation indexes, established the linear relationship between index variables and safety, and determined the comprehensive components risk value, to realize the quantitative evaluation of ventilation system. Use the software SPSS to realize the comprehensive evaluation of ventilation system situation. With this method, the result indicates that it does not only reduce the overlapped information level and simplifies the burden of hierarchical division, but also greatly lower the data processing work, which provides technical basis for safety production management and decision making.关键词
