煤矿重大瓦斯事故场景下应急行为观测实验

Experiment on Emergency Behavior Observation from Coal Mine Gas Accident Scene

采取行为安全观测方法,对某试点矿井发生煤矿重大瓦斯爆炸事故演练场景下的作业工人为样本人群,对作业工人应急行为进行观测实验,先后进行2次观测,观测时间都为整个应急演练全过程(2 h),并将2次观测数据进行对比分析,同时对观测实验的有效性进行问卷调查,并与预先设定的应急预案规程及演练脚本进行对比,进而矫正完善应急预案规程及演练脚本。结果表明,参演个体的6个工种经过2轮观测实验后,其作业中安全行为次数增长率依次为采煤工(37.5%)、采煤机司机(25%)、瓦监工(25%)、爆破工(25%)、机电维护工(25%)。2轮观测实验趋向对比中,增长率分别是5.63%、15.66%。有效性问卷分析显示,85%的参演人群认为应更多开展类似的应急行为训练工作,30%人对观测实验提出了很多改进的建议。

Taking safety behavior observation method, the workers in a pilot coal mine occurring major gas explosion accident were taken as samples, and the emergency behavior of the workers were observed, and the observation time was 2 times, and the two observation data were compared, and the effectiveness of the observation experiment was carried out, and the comparison with the pre-setting emergency plan and the exercise script, and then improve the emergency plan and the script. The results showed that the participating individuals of six types after two rounds of experiments, the job safety number growth rate followed by the drivers of coal miners （37.5%）, shearer （25%）, tile overseer （25%）, blaster （25%）, electrical and mechanical maintenance industry and trade （25%）. In the trend of the 2 round observation experiments, the growth rate is 5.63%, 15.66%. Validity of the questionnaire analysis showed that 85% of the participating population should be carried out more similar emergency behavior training work, 30% of the population in the observed experiment proposed many suggestions for improvement.
