摘要
为了探究噪声对不同风险感知水平矿工个体的安全行为能力的影响程度,明确噪声引起矿工的生理参数的变化程度与作业出错率的关系,采用量表与实验相结合的方法,将矿工分为风险感知水平不同的两组,分别测试两组矿工的眼手协调出错次数与平均心率(Mean HR)、平均皮电反应水平(Mean SCL),运用SPSS19.0对所得结果进行了显著性检验。结果表明对于风险感知水平不同的矿工,噪声对其眼手协调出错次数增加率的影响与其平均心率变化率、平均皮电反应水平变化率呈线性相关。研究结论表明噪声对风险感知较低的矿工安全行为能力影响程度较大,对风险感知较高的矿工安全行为能力影响程度较小。在此研究基础上,提出了防控对策。
In order to explore the noise influence and its degree on the behavior safety ability of miners whose risk perception levels are different, as well as to figure out the relationship between miners＇ physi- ological parameters changes result from noise and operating error rate, a method of combining question- naire and experiment is adopted in this paper. The method divided the miners into two groups according to their different levels of risk perception. Then, test two groups of miners in eyes-and-hands coordination mean error frequency, mean average heart rate and mean skin conductance level, and analyzes the obvi- ous changes in the result using SPSS19.0. The results indicate that：for miners with different risk percep- tion levels, due to noise influenced, miners＇ eye and hand coordination errors increase rate is related to the change rate of mean heart rate（HR） and mean skin conductance level（SCL） rate. The conclusion shows that safety behavior ability of miners with lower level of risk perception get greater impact from noise;on the contrary, safety behavior ability of miners with higher level of risk perception get less im- pact. Finally, we put forward the prevention and control countermeasures based on the conclusion.
