Monitoring of the mining waste neutralization facility of LW Bogdanka

unattractive areas is one of the most advantageous ways of
wastelands revitalization. In the case of post-mining dumps, it is
realized by using photovoltaics and wind turbines. Analyzes showed
that the greatest benefits can be acquired from photovoltaic farms,
mainly due to the simplicity of their design and principles of
operation, as well as the quick return on investment - up to 7 years.
The construction of wind turbines is more complicated. Despite the
favorable conditions of the mining dumps (elevated areas, which are
located mainly away from residential buildings), the construction of
the turbine requires more effort in designing and installation work,
mainly due to the necessity of building the foundations.
Methods for revitalizing mine dumps by installing renewable energy
systems have some limitations due to periodicity of operation (time
of day, season), weather conditions (wind speed, temperature),
expensive energy storage, etc. For this reason, real-time monitoring
of climatic conditions is required. The following parameters are
monitored: the average available solar energy (important for the
assessment of the efficiency of photovoltaic cells), speed and
direction of the wind (which affects the efficiency of wind turbines),
changes in groundwater level (risk of flooding and periodic soil
softening), soil and air temperature (air – affects the choice of the
method of revitalization, soil – affects the preservation of soil) and
dust concentration, which affects the degree of contamination of the
photovoltaic modules and thus the efficiency of the photovoltaic (PV)
power plant. The presentation includes interesting data that was
obtained during the tests
