Abstract

The growing demand for mineral resources, including hard coal, 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.

液压支架液压系统开发中的人为因素

对包括硬煤在内的矿产资源的需求不断增长，需要不断改进和发展技术，以提高安全性、生产力和性能。矿山自动化和数字化的实施已经进行了几年。机械和设备的开发和改进也在进行中。作者讨论了动力顶板支架的发展和改进，它是长壁系统的关键部分。动力顶板支架负责长壁作业设备和人员的安全。它支撑工作面和直接顶板，并在采煤机移除煤炭和护盾后面的顶板塌陷（采空）时向前移动长壁系统。本研究的目的是考察开发和改进动力屋顶支架液压支撑系统所涉及的人为因素。这项研究主要通过调查在硬煤矿井的员工中进行。这项研究使作者能够检查和分析矿工提供的关于工业4.0时代（第四次工业革命）动力屋顶支撑的信息。根据研究结果，矿工们预计电动屋顶支架的可靠性会有所提高，他们希望实时监控关键操作参数，尤其是所需的负载能力，以便进行调整和改进。研究结果指出了矿工的需求和期望。他们的意见应该决定动力屋顶支撑的方向和任何研究空白。

期刊介绍： Acta Montanistica Slovaca publishes high quality articles on basic and applied research in the following fields: geology and geological survey; mining; Earth resources; underground engineering and geotechnics; mining mechanization, mining transport, deep hole drilling; ecotechnology and mineralurgy; process control, automation and applied informatics in raw materials extraction, utilization and processing; other similar fields. Acta Montanistica Slovaca is the only scientific journal of this kind in Central, Eastern and South Eastern Europe. The submitted manuscripts should contribute significantly to the international literature, even if the focus can be regional. Manuscripts should cite the extant and relevant international literature, should clearly state what the wider contribution is (e.g. a novel discovery, application of a new technique or methodology, application of an existing methodology to a new problem), and should discuss the importance of the work in the international context.
