Approximately 30 million tons of tailings are being stored each year at the KGHMs Zelazny Most Tailings Storage Facility (TSF). Covering an area of almost 1.6 thousand hectares, and being surrounded by dams of a total length of 14 km and height of over 70 m in some areas, makes it the largest reservoir of post-flotation tailings in Europe and the s...

The Zelazny Most Tailings Storage Facility (TSF) is the largest reservoir of post–flotation tailings in Europe. The total amount of tailings from the mines in Lubin, Rudna, and Polkowice stored each year at the disposal facility reaches approximately 30 million tons. Accurate monitoring and maintenance of such a huge storage facility are crucial fo...

Ventilation and airconditioning are some of the most energy-consuming processes in deep underground mining. Additionally, the energy consumption of these processes systematically increases along with the expansion of the mine. Therefore, proper energy efficiency assessment and consumption forecasts of these systems are particularly important in mod...

This article presents the concept of using the DTW algorithm to partially solve the problem of locating LHD (load, haul, dump) in an underground mine. The concept assumes the recognition of characteristics—patterns that are hidden in vibrations recorded by vehicles—in segments of the route in the underground excavation, which under appropriate cond...

Currently, advanced data analytics in large multi-site industrial enterprises is a strategic element in making management decisions. Integrated supply chain management (SCM), machinery park management, or data analysis from industrial devices (including using Industrial Internet of Things - IIoT) requires the organization of appropriate analytical...

Measurement of structure deformation is one of the two most important elements in assessing the current operating condition of a hydro-technical facility, which is especially important when the object is under constant expansion. This is the case of KGHM’s Zelazny Most tailing dam which is the largest tailings storage facility (TSF) in Europe. The...

The Inertial Measurement Unit (IMU) is widely used in the monitoring of mining assets. A good example is the Polish underground copper ore mines of KGHM, where research work with the use of the IMU has been carried out for several years. The potential of inertial sensors was ensured by the development of advanced analytics using machine learning me...

In the article, a method of terrain recognition for robotic application has been described. The main goal of the research is to support the robot's motor system in recognizing the environment, adjusting the motion parameters to it, and supporting the location system in critical situations. The proposed procedure uses differences between calculated...

Growing demand for raw materials forces mining companies to reach deeper deposits. Difficult environmental conditions, especially high temperature and the presence of toxic/explosives gases, as well as high seismic activity in deeply located areas, pose serious threats to humans. In such conditions, running an exploration strategy of machinery park...

Maintaining a pavement in good condition is one of the key challenges faced by services responsible for road infrastructure. In particular, the poor quality of the surface may pose a serious threat to life and health and lead to serious damage to vehicles. The problem becomes much more serious in difficult environmental and road conditions. Moreove...

For many years now, the mining industry has seen a boost in exploring and developing the systems for monitoring operational parameters of mining machines, in particular load-haul-dump machines. Therefore, further researches on algorithmics have also advanced dynamically regarding effective performance management as well as predictive maintenance. N...

The haul trucks are one of the most often used assets in horizontal transport in underground copper ore mining. This haulage process has a cyclic form and in simple terms the machine drives from point A to point B, where its cargo box is respectively loaded and dumped. What is most important in its basic performance assessment is to identify each c...

This paper outlines the recommendation of analytical tools likely to be derived from the data recorded within the industrial automation system. The means might facilitate optimization of process efficiency, especially in terms of energy efficiency. Basically, each electromechanical device is electrically charged and controlled by the industrial aut...

Most of the machinery and equipment of the mine infrastructure is controlled by an industrial automation system. In practice, SCADA (Supervi-sory Control And Data Acquisition) systems very often acquire many operational parameters that have no further analytical use. The variability of recorded signals very often depends on the machine load, as wel...

Artykuł przedstawia propozycję narzędzi analitycznych, możliwych do opracowania z danych rejestrowanych w ramach funkcjonowania systemów automatyki przemysłowej. Narzędzia te mogą być realnym wsparciem przy próbie optymalizacji efektywności procesowej, szczególnie energetycznej. W uproszczeniu, każde dowolne urządzenie energomechaniczne zasilane je...

The development of advanced analytics for data measured by SCADA systems is crucial from the viewpoint of process monitoring, management, and optimization. Many mining assets are characterized by cyclical operations performed with a fixed sequence of their course. An example is the Load Haul Dump (LHD) machine transporting material from the mining...

Nowadays, the problem of ambient air pollution is a challenge in the world. Many government initiatives are being implemented to mitigate the impact of pollution on the environment as well as other aspects of human health and life. A particularly important case is urban areas exposed to the negative impact of industry, for example mining and power...
