Accident-causing mechanism in coal mines based on hazards and polarized management

摘要: Hazards are elements that could cause harm or loss and sources of risk. This paper classifies hazards associated with coal mining. Specifically, categorized into root status hazards, the further divided unidentified identified include controlled uncontrolled hazards. It also explores in some detail relationship between accidents accident-causing mechanisms. The mechanism “three layer defense” is proposed based on definition classification, including control criteria, measures, rectification which demonstrates two main sources. then ideas polarized management as a means maximizing identification their corresponding minimizing out probability caused by Finally, methods put forward respectively, root-status identification, formulation criteria measures.
