Special Issue Information

Dear Colleagues,

The transformation of the European economy toward a greener and more climate-friendly one is one of the most important tasks defined by the European Union. However, this is a particular challenge for mining regions, both in terms of the technological and social as well as economic aspects. The transformation process also includes the liquidation of underground workings and infrastructure surface development as well as a number of indispensable activities aimed at the restitution of the natural environment and protection of mine areas against hazards that may occur after the end of operation. Therefore, this infrastructure should be used for achieving the objectives of a Just Transition because it also generates an opportunity to invest in renewable energy sources and create new markets related to green energy, energy storage, and sustainable transport. Finally, the Just Transition also forms an opportunity to revitalize urban and natural areas and to repair the damage caused by the intensive exploitation of mineral deposits.

Despite the decline in hard coal and lignite production related to the energy transformation across Europe, the mining industry still needs modern machinery and equipment. Due to the descent to ever greater depths of extraction and the associated increase in natural hazards, the mining sector needs intelligent and even more automated technical solutions. In the coming years, hard coal mines may become important participants of the so-called Industrial Revolution 4.0, popularizing, inter alia, intelligent ICT systems and automating subsequent elements of production processes. The intelligent mine is to be characterized by state-of-the-art solutions
that translate into higher efficiency and an increase in miners’ work safety, enabling them to be separated from particularly dangerous workplaces.

The Special Issue aims to present the latest scientific, research, and technical achievements in the field concerned with the transformation of the mining sector, with particular emphasis on the issues of the Just Transformation, the Green Deal, as well as the exchange of knowledge and experience as regards the use of innovative techniques and technologies.

This paper presents a concept of a routing algorithm for a network of sensors monitoring the condition of machinery and equipment operating in areas at risk of methane and/or coal dust explosion. It was assumed that the proposed algorithm would find application in sensor networks monitoring, among other things, oil pressure in powered roof supports and the position of powered roof support elements. The results of a literature analysis were presented, which included the simulation of sensor network routing algorithms, including, among others, reactive algorithms, proactive algorithms and algorithms based on so-called swarm intelligence (SI). As a result of the analyses, several algorithms were selected and implemented in a prototype sensor network. The characteristics of each of these algorithms are described. The article includes a description of the commissioning work of the network, which consisted of between 3 and 30 nodes. An analysis of the collected measurement data obtained for each criterion of the performance evaluation of the routing algorithms is presented. Full article

This study presents the structure and principles of operation of the control system for a bucket conveyor operating in a jig preparation plant. The idea of controlling the conveyor speed is to maintain constant, nominal filling of the buckets, and thus achieve a constant mass of material on the conveyor. As part of the completed task, a new control algorithm was developed and implemented to increase transport efficiency. Simulation and industrial test results were analyzed, in which the traditional PID controller was replaced with a fuzzy controller, which enabled control error reduction, thus achieving better control quality.

A tailing storage facility (TSF) is a complex hydrotechnical structure that requires continuous monitoring to prevent catastrophic dam damage. One critical issue to control is the soil’s characteristics, which is why many field and laboratory tests are carried out on the dam to determine the relevant soil parameters. Among these tests, down-hole seismic tests, such as SCPT, are performed to determine, e.g., the shear wave velocity. However, accurately calculating the difference in the times of the arrival of the wave at the two geophones is crucial to determining its value. This article proposes a novel method for estimating this variable using the DTW (Dynamic Time Warping) algorithm, which calculates the shift between two signals by determining their optimal match. The article also addresses signal interference and proposes methods for clearing it to obtain more accurate results. Furthermore, the article introduces a method for measuring the signals’ quality based on their similarity, which helps assess whether determining the shear wave velocity is possible for a given sample.
