为了解煤矿安全性与灾害因素之间的关系,利用已有大量的安全记录作为基础数据,使用因素空间理论中的因素分析法对煤矿灾害安全性进行分析。论述了因素空间和因素分析法的基本特点,及目前定性安全评价中的问题。对所举实例分析表明:因素分析法可以挖掘出蕴含在安全信息中的灾害因素与煤矿安全性之间的因果关系,并可分析出所得结果的可信程度。该例煤矿灾害安全性因素决定度排序为:冒落〉瓦斯〉岩爆〉透水。基础信息比较客观,分析结果可信度为85.7%。
In order to understand the relationship between safety and disaster factors in coal mine, taking a large number of existing safety record information as the basis data, the safety of coal mine disasters was analyzed with factor analysis method in the theory of factor space.The basic features of factor space and factor analysis method were discussed, as well as the issues of current qualitative safety assessment.Through practical case analysis, it showed that:factor analysis method can dig out the causality relation between disaster factors in safety information and coal mine safety, and can analyze the reliability of obtained results.The order of safety factors of the case was caving>gas>rock burst>permeable.The basic information was more objective, and the reliability of analysis results was 85.7%.
