Limiting exposure to noise of miners servicing conveyor belts by situating their workstations within technological recesses

Abstract

The article presents a method of limiting exposure to noise in the vicinity or workstations of conveyor drive services. This is done by setting up the conveyor belt personnel’s workstations within special technological recesses. The core of the presented solution consists in the design of an optimal set up of the technological recess, which in turn has enabled the realisation of production activities with OSH taken into account. The necessary requirement was a simultaneous achievement of the value of the equivalent noise level A LAeq below the value of relevant health standards. The results of the measurement were superimposed on the schematics of the mining excavation, and thus decided about the placement of the solution. New workstations were created and located according to the same schematics with the use of one-way exit with roof and the front wall and the side walls made of straight cross-bars of V29 profiles. Additionally, to improve the acoustic climate, the constructed technological recesses went through the acoustic adaptation performed with the use of sound absorbing material. The solution has been implemented in Węglokoks Kraj Sp. z o.o. KWK „Bobrek - Piekary”.
