The article presents the results of measurements of environmental noise caused by devices operating in the
surface facilities of hard coal mines and by the technological processes related to the loading and transport of
spoil and materials necessary for production. The research results are part of the program “Consequences of
excessive noise in the mining environment of hard coal mines”, the overarching goal of which is to reduce the
emission of industrial noise. A sampling method was used to determine the actual values of noise levels emitted to the external environment from mines and mining plants as well as to identify the acoustic power levels
of devices and processes constituting the main sources of noise in mines. The results showed that mines and
mining plants are often not fully aware of the scale of the environmental impact of the undesirable noise they
emit. Therefore, the current periodic measurements of environmental noise should be replaced with permanent
monitoring, which will be beneficial not only for the environment and residents of housing estates located near
mines but also for the mining plants themselves.
