煤矿透水事故不安全动作原因分类研究
Research on Reasons Classification for Unsafe Acts in Coalmine Water Accidents
-
摘要: 为了减少和预防煤矿透水事故，依据事故致因“2-4”模型，利用统计学原理，对2000-2009年间的68个煤矿重特大透水事故中人的不安全动作进行分析、归类、统计。统计得到的413个不安全动作可以划分为2大类和6小类，统计结果表明：2大类中违章与不违章的比例分别为99.5%、0.5%；6小类中，违章指挥、指挥未执行的比例分别为32%、14%；违章操作、操作未执行的比例分别为21%和31%，不违章但可能导致事故与违章行动两者比例之和为2%。研究得出治理违章首要工作是通过培训，减少指挥、操作中的高频违章动作；提出了一种新的不安全动作分类思路。Abstract: In order to prevent water accidents, according to the accidents causation theory "2-4" model and using the statistical theory, taking the coalmine water accidents occurring during 2000 to 2009 as the research objects, we analyze the unsafe acts in the water accidents of 68 coal mines, and classify those unsafe acts and count the frequency. The research results show that the obtained 413 unsafe acts can be classified into two categories as well as six subcategories. Among the two categories, proportion of violation and non-violation is respectively 99.5%, 0.5%; among the six subcategories, proportion of violation command and non-command is 32%, 14% respectively, proportion of violation operation and non-operation is 21%, 31% respectively, and proportion of violation movement and non-violation is 2% together. The conclusions show that the primary job of controlling violation is to reduce the high frequency unsafe acts in commanding and operating by means of training, and a new method for classifying the unsafe acts is proposed.
