A simulation experiment study to examine the effects of noise on miners' safety behavior in underground coal mines.

摘要: BACKGROUND Noise pollution in coal mines is of great concern. Personal injuries directly or indirectly related to noise occur from time time. Its effects impact the health and safety mine workers. This study aimed identify if how level impacts miners' behavior underground mines. METHODS In order influence on miners mining industry, we built a simulation experiment system, set test at 50 dB ~ 120 dB according actual working environment well. We divided gradient into 8 categories conducted 93 experiments, which aim attention distribution, fatigue, reaction under each level, experimental results were analyzed by SPSS22.0 software. RESULTS The show that increase environmental will have an attention, reaction, fatigue. positively negatively reaction. environment, sensitivity personnel optic stimuli higher than acoustic stimuli. indicators change significantly, when greater 70 ~ 80 dB. CONCLUSIONS From perspective accident prevention, can be controlled within range less 70 ~ 80 dB, control occurrence accidents certain extent.
