Abstract：Noise pollution in fully mechanized coal face has a serious impact on the physical and mental health and safety performance of the workers. In order to study the effect of short-term noise exposure on workers' attention, using the Schulte grid and the relevant knowledge of human factor engineering, environment, physiology, experimental psychology and behavior, the effects of noise level and noise exposure time on workers' attention were analyzed and the corresponding regression model was established. The results showed that: ( 1) the noise stimulation level and noise exposure time had a significant effect on workers' attention. ( 2) the noise stimulation reduced the concentration of workers' attention. ( 3) when the noise level was less than 95 dB, it was the dominant factor that affected the workers' attention. While the noise level was more than 95 dB, noise exposure time was the main affecting factor.
