In this article, the current state of the art in the area of autonomously working and mobile robots used for inspections in deep underground mining and exploration is described, and directions for future development are highlighted. The increasing demand for CRMs (critical raw materials) and deeper excavations pose a higher risk for people and requ...

Belt conveyors are essential systems for the continuous transport of various materials across many industries, particularly in bulk material handling for mining. While they are often the most economical solution, they still consume a significant amount of energy. This article discusses the latest advancements and the current state of energy-saving...

Underground mines are a vital part of the European raw material industry. The subsurface mining process is related to the large-scale development of underground structures like tunnels, chambers, workings, etc. These structures are abandoned or liquidated during the process of exploitation or after the termination of works. Still, due to the unique...

Belt conveyor (BC) transportation systems are considered to be the most effective for handling large volumes of bulk material. With regards to the rules of sustainable development, the improvement of belt conveyor technology is, in many cases, focused on environmental issues, which include the idea of energy usage optimization. The key issue in an...

The transition from coal to a sustainable green economy poses a significant challenge for regions deeply rooted in mining. This research presents the diversity and complexity of socio-economic and environmental issues that characterize these areas. The article analyses the challenges related to the just transition of Polish mining regions and asses...

Current EU policy will force a significant reduction of hard coal mines in the near future due to environmental restrictions. There are also numerous non-coal underground mines that will be excavated in the next few years. Taking the above into consideration, it is worth starting to plan further steps in terms of reclamation of these facilities. Wi...

Theoretical and experimental research indicates that radial loads have a significant influence on the value of belt-on-idler rolling resistances. Computational models discussed in literature use the notion of unit rolling resistance, i.e. rolling resistance per unit length of the idler. The total value of the rolling resistance of belt on a single...

Conveyor belt and especially its cover is viscoelastic material, which means that it combines viscous and elastic properties at the same time. In calculation of motion resistance, mainly in indentation rolling resistance, equivalent lateral stiffness of belts if necessary. To determine this value the distribution of compressive stress (both, in cov...

Calculation of motion resistance of belt conveyor shown underestimation in comparison to results of conducted measurements. The main component of motion resistance for conveyors longer than 80 m are primary resistance. Furthermore, indentation rolling resistance can generate more than half of them. The disproportion between measured and calculated...

Assigning transported material with a supplementary information is becoming relevant for the needs of improving the efficiency of industrial processes. In the mining industry annotating the mined ore could bring benefits due to expected decrease of the processing ener gy consumption and increase of productivity. DISIRE project was focused on the im...

Belt conveyors are highly reliable machines able to work in special operating conditions. Harsh environment, long distance of transporting and great mass of transported martials are cause of high energy usage. That is why research in the field of belt conveyor transportation nowadays focuses on reducing the power consumption without lowering their...

Belt conveyors are main part of transporting systems in mines and in many other branches of industry. During conveyor belt works different types of resistances are generated. Indentation rolling resistance is the most significant component of the resistances from the perspective of energy losses and it cause the biggest costs as well. According to...

Belt conveyors, having high reliability and efficiency, are the main means of continuous transportation both in underground and in open-cast mining. Despite their numerous advantages, however, belt conveyors are expensive in maintenance. Therefore, improvements in the field of belt conveyor transportation largely focus on methods for lowering their...

Doskonalenie transportu taśmowego skupia się obecnie w coraz większym stopniu na obniżeniu energochłonności przy realizowaniu złożonych zadań trans-portowych. Obniżenie energochłonności przenośników taśmowych w bezpośredni sposób redukuje koszty eksploatacyjne. Aby zrealizować konkretne rozwiązania energooszczędne, konieczne jest prowadzenie zarówn...

Wyniki przeprowadzonych badań eksperymentalnych wskazują na konieczność zweryfikowania metody wyznaczania oporu toczenia taśmy po krążnikach. W obliczeniach tej składowej oporu ruchu przenośnika uwzględnia się parametry tłumiące taśmy. Zarówno współczynnik tłumienia, jak i moduł sprężystości taśmy przy cyklicznym ściskaniu poprzecznym wyznacza się...

Przenośniki taśmowe stanowią nieodzowny element układów transportowych w wielu gałęziach przemysłu, a przede wszystkim w górnictwie. Na trasie przenośnika o długości kilometra taśma jest podpierana przez kilka, a nawet kilkanaście tysięcy krążników (2500-12 500), co w skali całego zakładu generuje liczbę nawet kilkuset tysięcy [3]. Ze względu na sk...

All objects whose temperature is above absolute zero emit infrared radiation in the wavelength range of 740 nm to 1 mm. This range is between radio waves and visible light. This phenomenon related to thermal radiation is used in thermal imaging methods to measure values and distribution of temperatures on an inspected object. Thermal imaging metho...

Conveyor belts are the most common way of mechanical handling equipment in industry, especially in underground and open-pit mines. Maintenance of conveyor belts generate high costs, therefore energy savings belts have become popular in recent years. Constant development of continuous transport equipment and looking for savings implies necessary of...
