基于主成分分析法的煤矿事故类型统计分析

Statistical analysis of coal mine accidents based on principal component analysis

针对煤矿众多事故间复杂的内部联系,本文根据国家安全生产监督管理总局事故数据统计资料,基于主成分分析法对我国2008—2017年造成煤矿死亡事故发生的主要原因进行分析。得出导致事故发生的第一主成分、第二主成分和第三主成分,进一步分析得出煤矿事故主要是由瓦斯事故、透水事故、煤与瓦斯突出事故和顶板事故引起的,确定了事故原因之间的关联性,为煤矿安全生产提供科学依据。研究结论可为类似研究提供一定的借鉴。

For complex internal relationship between coal mine of accident,according to the state administration of production safety supervision and management of the accident data statistical data,based on principal component analysis in our country from 2008 to 2017,the main causes of death in coal mine accidents were analyzed.The first principal component of the accident,the second,and the third,a further analysis of coal mine accident was mainly caused by gas accident,flood,and roof accidents caused by coal and gas outburst accident,the correlation between the cause of the accident was settled,which provided the scientific basis for the development of coal mine safety production.The conclusions of this study can provide some references for similar researches.
