摘要
在确定突出特征指标统计原则的基础上,结合贵州523次突出事故资料,从突出类型、强度、始突深度及突出强度变化等方面系统分析了贵州煤与瓦斯突出的特征。采用数理统计方法分析处理了各影响因素下的突出强度数值,并利用主成分分析法分析了影响瓦斯突出的主要因素,指出作业方式是诱导煤与瓦斯突出的主要外力因素。
Based on determining the outburst characteristic index statistics principles, combined with 523 outburst accident data in Guizhou, through systematic analysis of coal and gas outburst characteristics in Guizhou from the aspects of outburst type, strength, outburst depth and intensity variation, mathematical statistical analysis method was used to process outburst value under each factor, and principal component analysis was used to analyze the main factors that affect gas outburst, practices is the external factor induced coal and gas outburst.
