ABSTRACT

The noise is an essential ecological problem for ventilation shafts. For the time being,
mine administrations have reacted to the complaints of the population with palliative
measures. These measures usually included a noise barrier (timber-metal structure)
positioned in front of the ventilator or air vent. A radical structural intervention taking
into account all components of the ventilation block is necessary for the solution of the
problem. The structural solution should meet a number of criteria for adequate structural
form, accessibility to the ventilation equipment for maintenance, easy disassembly,
durability, and adaptability to possible future technological modifications. This report
considers the optimal effect of the structural soundproofing intervention. The solution
of the problem is considered with the help of a case study.
