Theoretical analysis indicates an underestimation of the calculated values of resistance of conveyor belts in relation to the measurement results. Disproportions are mainly observed for large mass capacities of conveyors. In this paper previous method for calculations of indentation rolling resistance was improved. Indentation rolling resistance is the main component of motion resistance for conveyors longer than 80 m. The most important impact on rolling resistance have damping factor of belt. This parameter was included in calculations in the new approach, moreover, a defined way of its determination in laboratory conditions was indicated. Another important parameter is the modulus of elasticity affecting the transverse rigidity of the belt. By analyzing elastic energy in bottom cover and cord of the belt new equations (which included construction and belt type) were established. In addition, the impact of the distribution of the loads along the idler on the rolling resistance value was analyzed. On this basis different equations for calculations of center and side idler was proposed. New theoretical model was verified in both laboratory test and measurements conducted in mine conditions. A series of tests of rolling resistance and damping properties were carried out for belts of various core designs and various rubber of bottom covers. Damping factors and modules of elasticity established in laboratory conditions were applied to new calculations algorithms. Obtained results were compared with measured values. Final verification of the new theoretical model was a comparison of calculated resistance with measured values for conveyor in mine. The obtained results have much higher convergence than the previous calculations. The new calculations allows for more accurate dimensioning of the drive and other elements of the belt conveyor.

The paper shows the results of researching the rollers used in belt conveyors working in a hard coal mine. Rollers should be characterized by low rotation resistance, which results in low power consumption of the propulsion unit. The tests conducted aimed to assess the technical condition of the new C-type rollers after several years of operation in a hard coal mine. The research was carried out from the new approach to the standard issues of roll testing and verification in a hard coal mine. Laboratory tests were combined with testing the entire belt conveyor in terms of power demand. The research was carried out for 3 years and it was monitored how the dynamic resistance of the working rollers changed and how this translates into the power demand consumed by the belt conveyor in a hard coal mine. The aim of the research was a new approach to the research of rollers used in conveyors operating in a mine.

The article presents the detection of damage to rollers based on the transverse vibration signal measured on the conveyor belt. A solution was proposed for a wireless measuring device that moves with the conveyor belt along of the route, which records the signal of transverse vibrations of the belt. In the first place, the research was conducted in laboratory conditions, where a roller with prepared damage was used. Subsequently, the process of validating the adopted test procedure under real conditions was performed. The approach allowed to verify the correctness of the adopted technical assumptions of the measuring device and to assess the reliability of the acquired test results. In addition, an LSTM neural network algorithm was proposed to automate the process of detecting anomalies of the recorded diagnostic signal based on designated time series. The adopted detection algorithm has proven itself in both laboratory and in-situ tests.

The publication presents the results of measurements of the operating parameters of the drum drive of a belt conveyor operating in a copper ore mine. The laboratory and industrial tests of belt conveyor components so far have largely focused on idler sets, the belt and the conveyor route. The authors of the publication notice that the subject literature lacks information on research into the coefficient of friction between the belt and the drum in an industrial facility under real conditions, which may imply that the phenomenon of driving force transmission from the drum surface to the belt has not been thoroughly explored. The investigations described in the publication were aimed at determining the kinetic coefficient of friction between the conveyor belt and the lining of the drive drum under operating conditions. In the first part of the study, preliminary laboratory tests were carried out, whereas in the second part of the study, a mobile, non-invasive measurement system was applied, which allowed for recording the kinematic and dynamic parameters of the conveyor’s operation. During the several dozen minutes of the conveyor’s operation, there were several start-ups and brakings as well as periods of steady operation under variable load on the material handled. The non-typical planned sequence of switching on the drive motors caused a temporary slip of the belt on the drive drum surface during one of the start-ups. The recorded parameters of the conveyor operation enabled determining the operational limit value of the friction coefficient between the belt and the lining of the drive drum.

The paper presents the description and results of experimental research whose purpose was to analyze the vibration influence the miner's body during riding on a belt conveyor for transporting coal. The transport of people on mining belt conveyors is a commonly used method to increase mining efficiency and improve a mine's profitability. The paper presents an assessment of safety and comfort parameters used in transporting people, the effect of strong vibrations on the human body and its internal organs, the measuring system used to record the accelerations during the experiment and the measurement results. The recorded data enabled a dynamic analysis of the movement and an assessment of safety and comfort of transported miners on the basis of defined indicators. The data included the accelerations from the moment of getting on the conveyor belt to the moment of going down onto the platform. The tests were carried out for two different belt conveyor speeds, which allowed to assess how conveyor speed affects safety and comfort of people transported on the mining belt conveyor.

Zgodnie z wymaganiami polityki ekologicznej, działania kopalń odkrywkowych w zakresie ochrony środowiska powinny mieć charakter kompleksowy i uwzględniać muszą zasadę zrównoważonego rozwoju. Jedno z podstawowych zadań w tym obszarze dotyczy redukcji uciążliwego hałasu emitowanego do środowiska. W przypadkach eksploatowanych ciągów transportowych skuteczna walka z ponadnormatywnym hałasem jest możliwa dopiero po szczegółowym rozpoznaniu głównych źródeł jego powstawania. W oparciu o studia literaturowe opisano możliwe źródła hałasu towarzyszące pracy przenośnika taśmowego. W dalszej części artykułu przedstawiono badania rozpoznawcze źródeł hałasu. Badania przeprowadzono w warunkach laboratoryjnych z wykorzystaniem kamery akustycznej, jako narzędzia pozwalającego na identyfikację w przestrzeni i klasyfikację poszczególnych źródeł hałasu.

In accordance with the requirements of the ecological policy, the operation of opencast mines in the field of environmental protection should be comprehensive and must take into account the principle of sustainable development. One of the basic tasks in this area concerns the reduction of nuisance noise emitted to the environment. In the case of exploited transport lines, an effective fight against excessive noise is possible only after a detailed identification of the main sources of its generation. Possible sources of noise accompanying the operation of the belt conveyor have been described based on literature studies. The further part of the work presents identification tests of noise sources. The research was carried out in laboratory conditions with the use of an acoustic camera as a tool allowing for the spatial identification and classification of individual noise sources. Selected phenomena accompanying the operation of the main components of the conveyor have been identified and their characteristic frequency ranges assigned to them.

The article presents the results of research of the Gwarek 1200 belt conveyor. The work aimed to determine the possible benefits of changing the type of rollers used. It was expected that the change of the rollers from N-type to C-type will reduce the costs of energy consumed by the conveyor drive system. This part of the research was carried out in a hard coalmine at the level of 665 m. The test was given the entire power unit in terms of the starting power demand and rated power in real time. Measurement works were carried out before and after the modernization of the conveyor for 5 years. Moreover, it was decided to extend the research to include vibroacoustic tests, aimed at determining the technical condition by measuring vibrations. It is expected that based on the analysis of vibration signals in the long term will allow to develop a method for diagnosing belt conveyor rollers and to quickly detect their malfunction under normal operating conditions.

The publication presents the construction of the station for testing the friction coefficient under high pressure and low slip velocity values. These conditions of cooperation of friction pairs occur in the drives of transport machines such as belt conveyors and suspended monorails. The value of the friction coefficient, depending on the operating conditions such as moisture and rock or coal dust pollution, has a significant impact on the correct and efficient operation of such drives. The features of the station allow mapping the operating conditions on a laboratory scale. As part of the research, appropriate friction samples made of rubber or polyurethane were prepared. Referring to the conditions of conveyor operation and conditions of contact of the conveyor belt with the drive drum, the values of unit pressures and values of slip speed occurring in the drum drive of the belt conveyor were determined. A series of laboratory tests were carried out for the friction pair rubber drum lining – conveyor belt cover. The tests were carried out for four different states of friction vapor surfaces, namely for dry and wet samples, as well as for samples in clean or contaminated with stone dust. As a result of the tests, the values of friction coefficients for various surface states were determined, which will be valuable information for designers of friction drive systems of transport devices.

As we are increasingly focusing on the economy of mining, researchers are constantly trying to find new technologies to improve existing machines to be more efficient and less perishable. Such actions allow mining companies to save money in all of the mining processes. The authors focused on the transport of materials and how to improve it. The most frequent problems in this matter are caused by the destruction of conveyor belts. The cost of repairs is estimated at about half a billion crowns in the Czech Republic. That is why engineers are working on reduction of the rock impact force on the conveyor belt. The paper deals with the issue of reducing the passage of conveyor belts by proposing a new solution to the impact stand, which will considerably reduce the number of conveyor belt breaks.

This paper explores the possibilities of using an acoustic camera as a tool that allows the verification of the correct construction and operation of individual elements of a belt conveyor. Based on the simultaneously recorded components - a video camera and measuring microphones, the sound pressure level map of the belt conveyor was created. The tests were carried out in laboratory conditions and covered the location and identification of individual noise sources. The verification consists not only of searching for dominant sound sources, but above all, of searching for frequencies in the analysed spectrum that should not occur during their proper operation. The tests allow for the identification of frequencies and the determination of the sound pressure level for three noise sources: the electric motor noise, the idler roll bearing noise as well as the noise on the tail pulley caused by belt misalignment.

Narzędzia te mogą być realnym wsparciem przy próbie optymalizacji efektywności procesowej, szczególnie energetycznej. W uproszczeniu, każde dowolne urządzenie energomechaniczne zasilane jest prądem i sterowane systemem automatyki przemysłowej. Postać sygnału zwykle zależna jest od różnych trybów pracy danego urządzenia, wynikających m.in. z jego obciążenia zewnętrznego. Dostępne metody segmentacji sygnałów i metody statystyczne pozwalają zautomatyzować proces identyfikacji trybów operacyjnych, jak również rozpoznawać inne prawidłowości czy anomalne zachowania, wynikające z nieprawidłowej pracy urządzenia. Dzięki temu z prostego sygnału prądowego możemy liczyć rzeczywisty czas pracy obiektu technicznego, zużycie mediów, identyfikować tryby pracy urządzenia, rozpoznawać straty procesu, określać parametry wydajnościowe KPI oraz rozwijać procedury diagnostyczne.

This paper outlines the recommendation of analytical tools likely to be derived from the data recorded within the automation system (SCADA). The means might facilitate optimisation of process efficiency, especially in terms of energy efficiency. Basically, each electromechanical device is electrically charged and controlled by the SCADA. A kind of the signal usually depends on various operational modes of the given device which are classified by its external load. Available signal segmentation and statistical methods lead to the automatic identification of these modes and operational patterns or abnormal performances caused by poor technical condition. Therefore, simple electrical signal allows to count the real device performance time and utilities usage, to identify its operational modes, to recognise process losses, to specify KPI factors and to develop diagnostics. This paper describes multidimensional processing of conveyor stream data along with their exemplary use in real-time data. The algorithm of identifying operational regimes is characterised based on machine learning and further in-context analyses paired with visualisations.
