Human Factors in the Development of the Hydraulic System of the Powered Roof Support

requires the continuous improvement and development of
technologies to improve safety, productivity and performance. The
implementation of automation and digitization in mines has been
ongoing for several years. Machinery and equipment development
and improvement is also ongoing. The authors discuss the
development and improvement of powered roof support, which is a
critical part of the longwall system. The powered roof support is
responsible for the safety of equipment and people working in the
longwall. It supports the face and immediate roof and moves the
longwall system forward as the shearer removes the coal and the roof
collapsing (goafing) behind the shields. The aim of this study was to
examine the human factors involved in the development and
improvement of the hydraulic support system of powered roof
support. The research was carried out among employees in hard coal
mines using mainly surveys. The research allowed the authors to
examine and analyze the information provided by the miners
concerning powered roof support in the era of Industry 4.0 (the
Fourth Industrial Revolution). According to the research findings,
miners expect improvement in the reliability of the powered roof
support, and they want the key operating parameters, especially the
required load capacity, to be monitored in real-time so adjustments
and improvements can be made. The results of the research point out
the needs and expectations of miners. Their opinions should
determine the direction and any research gaps into powered roof
support.
