摘要
在利用人因分析和分类系统(HFACS)对同一组煤矿安全事故报告进行分析时,常会出现不同分析人员得出不同分析结果的情况。为解决这一问题,根据分析过程中是否反馈分析结果,设计煤矿安全事故人因的开环和闭环分析方法。以山西汾西煤矿集团的10起安全事故为样本,对不同分析人员应用2种方法得出的结果进行Cochran-Q检验,进而比较2种方法的优缺点。结果表明:闭环分析方法能较快地使分析结果满足一致性条件;开环分析方法能够充分保持分析人员的独立性,且分析结果的一致性主要取决于HFACS指标内涵及其表现形式的描述。
When HFACS is used to analyze one specific group of coal mine accident reports, it is common to see various conclusions may be drawn by different analysts. In order to solve this problem, the open-loop analysis method and a closed-loop analysis method were designed. 10 accidents of Fenxi Coal Mine Group Co. were used to analyze the results of two designed methods through Cochran-Q test. Furthermore, the advantages and disadvantages of two methods were compared. The results show that closed-loop method can let analysis results quickly meet consistency condition, that open-loop method can sufficiently maintain the independence of analysts, and that consistency of analysis results depends on de- scription of HFACS indicators connotation and their manifestations.
