Modeling acoustic effect exerted on personnel by operating equipment in underground coal mining

The review of the major researches into evaluation of industrial noise impact on underground miners reveals the consequences of such impact. The studies into combating increased noise are specified. Based on the review, it is concluded on the relevance and significance of the problem connected with the noise load evaluation and noise control in underground coal mining. In connection with this, the present study was aimed at modeling acoustic effects exerted by operating equipment as an abnormal acoustic source on underground coal miners. Using the standard procedure and license program, the noise pressure was calculated in a model roadway. The mathematical calculations and estimates of noise in the influence zone of operating mining equipment in a roadway are presented. The change in the noise pressure generated by operating equipment is determined at a distance to 40 m from the noise source. It is found that the noise pressure standards are exceeded at a distance to 20 m from the noise source, which may be the cause of an occupational disease—perceptive deafness. It is required to continue development of a monitoring and warning system to inform miners on the higher noise load in the course of underground coal mining.

Keywords: coal industry, industrial noise, perceptive deafness, noise standardization, noise source, noise propagation modeling, personal protective equipment.
