Because The Analysis And Classification Of Coal Mine Accidents Based HFACS People

In China’s current coal mine safety accidents, human factors relatedaccidents account for a large proportion. The human factor is one of theimportant reasons for the high occurrence rate of coal mine accidents in ourcountry. Therefore, the study on the classification of the human factors of coalmine safety accidents has a very important significance in reducing theoccurrence rate of coal mine accidents in China.The Human Factors Analysis and Classification System（HFACS）is animportant tool to analyze the cause of safety accidents, and has been widelyapplied to the investigation of safety accidents in aviation, railways, coal mine,medical and other industries. However, HFACS is a human factors analysismodel originally based on aviation safety accidents. When using HFACS toanalysis the coal mine safety accidents report, HFACS indicators and the causeof the accident in the report could not be corresponding or its correspondingrelationship has a certain ambiguity. This leads to the inconsistent HFACSanalysis results from different people when the same accident report is used.Based on the actual situation and characteristics of China’s coal mine, thepresent thesis would like to make a supplement to the details of HFACS, aimingat improving the consistency of HFACS analysis, and thereby facilitatingapplication of HFACS framework in coal mine.In present thesis, the accident reports of a Shanxi coal mine group from2006to2012are collected and classified. HFACS framework is applied, andSPSS19.0is adopted to collect and classify the causes of the160typical coalmine safety accidents. Chi square test and odds ratio (OR) are used to analysisthe management organization flaw, the causes for unsafe behavior, and theirinterrelationships. Research results show that the coal mine group managementorganization flaw is mainly reflected in the management process loopholes andlacking of management culture. Unsafe behaviors are typically embodied as skillerrors and violations. However, the loophole in the management process is the fundamental and underlying cause of unsafe behavior.Finally, based on the coal mine HFACS framework and by means of coding,the data descriptions of the accidents’ basic information are formed, such as thetime of the accident, location of the accident, the enterprise of the accident,accident type, the nature of the accident, the death toll, the number of seriousinjuries, the economic losses (million), human factors resulting in coal mineaccidents, and other information. This facilitates the coal mine accidents’archiving, searching and network management, and is also beneficial to thestatistical analysis of the coal mine safety accidents and the finding of solutionsto safety problems.
