摘　　要：煤矿井下噪声会对矿工作业产生不良影响,甚至会导致生产安全事故发生。为探究煤矿井下噪声对矿工反应能力的影响,减少因井下噪声导致的生产安全事故,采用实验测量的方法,分别对对照组和实验组施以50,80与90 dB噪声刺激,运用BD-V-509多项反应时测试仪记录在不同等级噪声刺激下被试的指尖脉搏、皮肤电、心率、呼吸频率等指标变化。运用SPSS 25.0对记录结果进行显著性分析。结果显示,在噪声刺激下,呼吸、心率、皮肤电和指尖脉搏等各项生理指标均出现显著变化。呼吸、心率、皮肤电和指尖脉搏等生理指标可以测试生理与精神状态;矿工反应时间可以作为测量矿工反应能力的指标,噪声的刺激会导致矿工反应能力变慢。井下作业中,应减少井下噪声源、降低噪声分贝,从而减少井下人因事故的发生。The coal mine noise has impact on miners’safe operation,which can easily lead to accidents.In order to explore the effects of noise on miners’reaction ability and reduce accidents caused by noise,the control group and the experimental group were subjected to 50,80 and 90 dB noise stimulation.BD-V-509 multi-response time tester was used to record the changes of such indicators as fingertip pulse,skin electricity,heart rate and respiratory rate of the subjects under different decibel noise stimulation.and SPSS25.0 was used to analyze the significance of the recorded results.It was found that respiration rate,heart rate,skin electricity and fingertip pulse showed significant changes under different decibel noise stimulation.The results indicated that physiological indexes such as fingertip pulse,skin electricity,heart rate and respiratory rate can measure physical and mental states and the reaction time can be used as an index of the miners’reaction ability.When the miners were stimulated by noise,the reaction time became longer and the reaction ability became weather.In the underground operation,the noise source and noise decibel should be controlled to reduce human-factor accidents.
