Abstract

Abstract:

In order to improve the evaluation system of coal miners' health damage and improve the level of miners' occupational health protection, this paper first evaluated the risk of dust and noise in the coal mine operating environment, and further adopted the health risk assessment and health damage quantitative assessment methods to establish the evaluation model of miners' dust and noise damage, and carried out health damage assessments for different types of work, and finally quantified the occupational health risk of miners in the form of currency. The results show that the risk level of coal mine dust and noise in the process of operation is the possible risk level, and the miners' health risk assessment model can be used to evaluate the health damage of miners caused by dust and noise. Except for all kinds of drivers and tunnellers in the high extraction roadway of Wu₈-31200 air tunnel, other types of work are affected by coal dust, and the impact of silica dust on miners is more serious under the same dust concentration. Within the same sound pressure level range, the older the workers are, the more serious the health damage caused by noise interference. At the same time, the type of work most affected by dust and noise is tunneling workers, whose occupational health risk is more than 13 000 yuan. The order of the occupational health risks in different places is as following: Wu₁₀-32040 air roadway, Wu₈-31200 air roadway high extraction roadway, Wu₈-32060 mining face, screening building, and storage and transportation team.

Key words: underground coal mine, working places, occupational health damage, dust, noise, health risks evaluation
