“…The requirements of reducing the manufacturing costs, increasing the efficiency, as well as improving people's working conditions and limiting their presence in risk zones make it necessary to look for new solutions, often based on automation, not only in industrial production enterprises [1,2], but also in the mining industry [3]. Increasing the degree of automation in hard coal mines where various types of threats to the safety of employees are present is one of the issues requiring intensive studies, but special technical and legal requirements mean that solutions from other industries, and even from the mining industry, cannot be easily implemented [4,5]. Issues related to the system being developed that allows for precise determination of the position and orientation of the mining roadheader during drilling of roadways in a hard coal mine are this article's subject.…”

The article presents tests on the possibility of using ultrasonic transducers for accurate distance measurement in hard coal mines. In order to check the impact of selected disturbing factors on the measurement results, test stands were built, and then a full cycle of measurements with the use of different transducers (AR30 and AR41), which were selected and pre-tested in previous research projects, was realized. The impact of such disturbing factors as airborne dust (coal, stone, lime and mixed dust), changes in temperature and humidity on the propagation of ultrasonic waves, amplitude and measurement accuracy was investigated. The tests were preceded by theoretical analysis. It was found that the transducers selected for the tests had a sufficient accuracy and range, so they can be used in the devices planned to be designed, allowing for the determining of the location of a roadheader in hard coal mine roadways, taking into account technical and legal restrictions. It was also specified which disturbing factors should be compensated and what methods and parameters of this compensation should be used.

This paper deals with the automation of the rock cutting process with roadheaders used widely in civil engineering for drilling roadways in underground mines and tunnels. Although there has been intensive technical development, roadheaders are still manually controlled. Manual control does not allow optimizing the values of the cutting process parameters, which often results in low mining efficiency, especially in the case of hard rocks, as well as high energy consumption and significant dynamic overloading of the roadheader. As part of theoretical and experimental research, an automatic control system was designed for the boom-type roadheader and an algorithm was developed for the optimal control of the cutting process parameters. Control criteria have been formulated, based on which the current values of the cutting process parameters are worked out using the information on the dynamic load state of the roadheader. The paper presents selected results of numerical tests conducted on roadheader dynamics, which simulated the automatic control system operation of the heading face cutting process of drilled roadway or tunnel. These tests were intended to analyze the behavior of the investigated object during simulated rock cutting in automatic mode. The results confirmed the possibility of a significant reduction in mining energy consumption.

“…Underground Coal Mining is a very challenging environment regarding the safety of the miners, dealing with heavy machinery in complex situations and harsh conditions. The digitization and automation of specific mining operations allows the development _________ of technical solutions to increase the safety and productivity in underground mining conditions (Jasiulek et al 2019). Various research and development projects as well as the INESI-project started in July deal with digitization and automation of the different processes within mining operations to increase resource efficiency, productivity and safety in underground mining.…”

Within the INESI-project (Increasing Efficiency and Safety Improvement in Underground Mining Transportation Routes) long-wavelength infrared (LWIR) cameras are used for detecting persons on underground belt conveyors or within hazardous areas e.g. in front of crusher or skip vessels by the project partners KOMAG and the Institute for Advanced Mining Technologies (AMT). The test case for evaluating the performance of thermal imaging regarding these applications is the Polish Sobieski underground coal mine operated by Tauron mining company. By the development of thermal image processing algorithms, an automated detection of persons and classification of different objects was achieved. This may allow implementing smart services for person detection on underground belt conveyors as well as material characterization between coal, rock and disturbing objects on belt conveyors.
