| 摘 要： | 煤与瓦斯突出危险性受多个因素的影响,且各因素之间彼此具有一定的相关性,导致在对煤与瓦斯突出危险性分析评介时在一定程度上有重叠。利用主成分分析法,将各影响因素组合为几个不相关的综合指标,建立煤与瓦斯突出危险性评价的数学模型,简化了煤与瓦斯突出危险性评价的数据分析,为客观、准确评价煤与瓦斯突出危险性提供了依据。

| Abstract: | The risk of coal and gas outburst is influenced by several factors,and there is a certain correlation among the factors,which lead to a certain extent overlap among the factors in coal and gas outburst risk analysis.Using the principal component analysis,several unrelated comprehensive indexes are combined by each influenced factor,and the mathematical model of coal and gas outburst risk evaluation is established,which simplifies the data analysis of coal and gas outburst risk evaluation,and provides a basis for objective and accurate evaluation of coal and gas outburst risk. |
