Special Issue Information

Dear Colleagues,

As a crucial foundation of modern human civilization, mineral resources support the operation and development of various industries in society.  Facing the rapid growth of the global population, how to safely,  efficiently, and greenly mine mineral resources has become an important issue for humanity today. The advancement in technology and the progress of new-generation information technologies have led to the increasing application of advanced techniques, concepts, and equipment in mines. A wide range of scholars and enterprises are also conducting research and practical efforts to enhance the level of mine intelligence. For instance, through the integration of advanced sensors and multi-source data fusion, robust perception has been achieved in harsh environments; the deployment of unmanned intelligent equipment has constructed intelligent fully mechanized mining faces; autonomous driving technology has been applied on a large scale in open-pit mines, enabling robotic operations in multiple stages such as drilling, blasting, mining, transportation, and dumping, significantly reducing the number of personnel and the labor intensity of miners; big data and large models have facilitated the construction of comprehensive dispatching platforms, enhancing production efficiency and lowering operational costs for mining enterprises; reclamation of mined lands and tailings treatment have greatly promoted harmony between the mining industry and the natural environment. However, with the development of deep, low-grade, and adverse geological conditions mines, reducing personnel, improving efficiency, and enhancing safety still face significant research challenges. The level of intelligent mine construction remains urgently in need of improvement.

Proposing and implementing new mining technologies, and advancing the development of geotechnical engineering, will contribute to the efficient extraction and green exploitation of resources, thereby elevating the current and future levels of mine development.

Shafts play a key role in the operation of mining plants. They connect underground excavations with the surface and provide the ability to transport people, equipment, and raw materials. The nature of the dynamic interaction of a conveyance moving at a significant speed along deformed guide rails is complex, and the method of assessing the interaction of hoisting conveyances with shaft steelwork, despite ongoing research, still requires further understanding and improvement. Misalignments of the guide rails and conveyance movements transverse to the shaft axis induce impact (guiding) forces, which are the key design parameters of shaft steelwork. The reliable assessment of guiding forces allows the design of safe and economical steelworks and the assessment of their structural safety during operation under deformations and corrosive deterioration. Determining the value of guiding forces requires their field measurements or the use of approximate empirical formulas. Both methods have their limitations—measurement is expensive and interferes with normal shaft operation, while empirical formulas are subject to high error due to the lack of consideration of many structural details specific to each shaft that significantly affect the behavior of the system. This study presents a new method for using a relatively simple-to-implement measurement of hoisting conveyance acceleration to assess guiding forces. A finite element model of the skip and steelwork was built, and simulations of the conveyance interaction with the structure were carried out. A strong relationship between the sliding plate’s impact point location and the guiding force was found. Extreme values of the guiding force were observed in the vicinity of the bunton connection. The study showed that reducing the skip load mass does not affect the force value. Simplified methods of calculating the moments of inertia of the hoisting conveyance significantly overestimate the code-based values of the guiding forces. The presented method considers the actual stiffness and mass distribution of hoisting conveyance and, therefore, allows for a more accurate estimation of the guiding forces and the transport of larger loads. This data-driven approach allows for the continuous monitoring of the guiding forces, the adjustments of the hoisting parameters, the rational planning of repairs, and a reduction in the replacement of corroded shaft steelwork.

Corrosion is a major problem in the mining industry, significantly affecting the durability and reliability of mining equipment. In order to better evaluate and understand these effects, in the first part of this study, the analysis by the finite element method of the metallic structure of the rotary arm of an ERc 1400-30/7 bucket excavator type, produced in Romania in 1985, is presented. This paper presents an analysis of the impact of corrosion on the structural integrity of mining equipment. The focus of the research is on the use of advanced spectral analysis methods and the implementation of wavelet analysis. These methods allow an increase in the degree of accuracy of the information and results obtained. The study also focused on the impact of corrosion on the natural frequencies and structural changes in mining equipment, which were evaluated based on advanced methods of structural analysis. The obtained results show that corrosion deeply affects the dynamic behaviour of the metallic structure, leading to significant changes in the dominant frequencies. It was found that the measured dominant frequencies show a tendency to increase with the increase of structural degradation, an observation that is consistent with the physical aspects of the phenomenon.
