瓦斯灾害主控因素分析方法研究

摘要

从瓦斯灾害复杂影响因素中提取主控因素是瓦斯灾害预测与控制的关键.偏最小二乘回归分析方法(PLSR)可以解决样本数据偏少以及自变量多重线性问题.文中采用PLSR进行瓦斯灾害影响因素的主控因素分析,通过实例分析表明此方法可靠性高,预测效果好.%How to extract the main controlling factors from the complex gas disaster factors is a key to gas hazards prediction and control. The method of partial least-square regression analysis can solve the multi-linear problem of less sample data and independent variable. In this paper, the PLSR is adopted to analyze main controlling factors of gas hazards. An case analysis shows this method is reliable.
