The efficiency of longwall systems in the case of using different cutting technologies in the LW Bogdanka

development of the mining industry, i.e. on the management of
fossil fuels deposits to achieve economic efficiency, environmental,
as well as social acceptance. It should be borne in mind that Poland
still belongs to the countries in which electric energy production
and thermal energy production are based on hard coal and lignite.
The research work results described in the article present efficiency
assessment aspects in the case of different longwall technological
systems in the LW Bogdanka. Advantages and disadvantages
resulting from using shearer and plow systems are given. An impact
of dilution in the run-of-mine on the coal quality is analyzed, and
some recommendations emerging from this analysis are suggested.
On the basis of the conducted in situ experiments, technical
possibilities of reducing dirt are described. As an efficiency
assessment is a multi-criterion process, so it requires continuous
monitoring of production parameters. The article also contains an
analysis of longwall systems in the aspect of dust control. An
impact of mining, technical and technological parameters on
generated dust amount, in particular in the case of a shearerequipped longwall face, is discussed. In the conclusions, it is
highlighted that an efficient assessment process in the case of
longwall systems is complicated as an impact of different factors
should be taken into consideration. It is suggested to use the data
integration platform based on the Service Oriented Architecture
(SOA). Due to the SOA, any mistakes in the scope of the
functionality of individual systems can be detected very quickly.
Such an approach is fundamental for the realization of the TPM
(Total Productive Maintenance), leading to the creation of the socalled Mine of Smart Solutions.
