Intelligent Management in the Mining 4.0
The achievements of the Fourth Industrial Revolution, embodied in “end-to-end” digital and convergent technologies, are able to ensure the stable development of the mineral resource sector in the face of fluctuations in raw material demand and the profitability of mining enterprises, strengthening environmental safety legislation. Mining 4.0 is also a response to the technological shocks associated with the accelerated digital modernization of the manufacturing and infrastructure industries. Mining 4.0 is a relatively new platform that allows, with the help of digital innovations, to move to more advanced production optimization.

Mining Geomatics
Mining geomatics is the knowledge and ability of using information systems to integrate and process spatial data about objects and phenomena occurring in the mining space in a way that enables the modelling and design of mining activities together with monitoring and visualising their state, analysing their changes and forecasting the effects of mining operations.

Application of UAV Photogrammetry in Mining Areas
The geological environmental damage caused by coal mining has become a hot issue in current research. Especially in the western mining area, the size of the mining working face is large, the mining intensity is high, while the surface movement and deformation are more intense and wider. Therefore, it is necessary to effectively monitor the surface using appropriate means and carrying out research on the overlying strata structure of the stope.

Diagnostics of Bolted Joints in Vibrating Screens
The condition-based maintenance of vibrating screens requires new methods of their elements’ diagnostics due to severe disturbances in measured signals from vibrators and falling pieces of material. The bolted joints of the sieving deck, when failed, require a lot of time and workforce for repair. Dynamical effects are investigated, which can occur due to bolted joints' degradation. Based on a reduced order dynamical model, important potential issues in screen design are discovered and new methods of diagnostics are developed.

Soft Computing Application in Mineral Processing
The mining sector has increasingly embraced simulation and modelling techniques for decision-making processes. This adoption has facilitated enhanced process control and optimisation, enabling access to valuable data such as precise granulometry measurements, improved recovery rates, and the ability to forecast outcomes. Soft computing techniques, such as artificial neural networks and fuzzy algorithms, have emerged as viable alternatives to traditional statistical approaches, where the complex and non-linear nature of the mineral processing stages requires careful selection.

Micro-Mineral Particle Slurry Rheometry
In mineral flotation operations, the mineral slurry is usually treated via grinding, agitation, flotation, and transportation, and the micro-particle slurry is often mixed with chemical reagent (mill and agitation tank) under such conditions, with air bubbles being separated under certain shearing fields in water-used equipment, such as a flotation cell or column. One characteristic of the micro-mineral slurry is polydispersity, including size and shape.

Mitigating Risks in Coal Mining
Insufficient stability of the top plate at the corner of an easily combustible coal seam comprehensive mining face may lead to a natural fire within the goaf. While corner sealing is crucial for minimizing air leakage, current sealing methods struggle to effectively prevent such leakage. Additionally, the distribution characteristics of the oxidation zone in the goaf after sealing are unclear, making it difficult to control the extent of the oxidation zone.

Quantum Chemistry in the Study of Flotation Reagents
Flotation reagents are significant for modifying the interfacial characteristics of mineral grains to achieve the effective separation of minerals. Since the 1960s, when quantum chemistry was first introduced into the study of flotation reagents, many achievements have been made, although some controversial topics remain.

Estimation of Muckpile Fragmentation Methods
Blasting is a very effective method of crushing various types of rocks with different hardness in mining, as it can crush a large amount of rocks at once and at a low cost. In addition, muckpile fragmentation is represented by particle size distribution, which is an important parameter for optimizing blasting plans. Methods for measuring the particle size distribution of muckpile fragmentation include sieving and using laser scanners, and methods using 2D images.

Unmanned Aerial Vehicles in Mine Closure/Rehabilitation Projects
Unmanned aerial vehicles (UAVs) are being used more frequently nowadays because of advancements in sensor and control technologies. They can use a range of single-band, multispectral, and hyperspectral sensors, including those that function in visible, infrared, and microwave spectrums. Their application in heritage and archaeological site mapping, transportation, civil engineering, agriculture, landscape mapping, wildlife conservation, infrastructure inspection, and search and rescue have been investigated in several studies.
