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.

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.

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.

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 Equipment Management
Mining sector is an economic foundation and the main source of national wealth for many countries. Modern mining operations are ever more reliant on efficient usage of costly large-scale mining equipment (e.g., trucks, shovels/excavators/loaders, conveyors and crushers). Thus, mining equipment management is becoming crucial for the mining industry. To be viable and sustainable, mining enterprises need to operate different types of mining equipment units at various stages with the objective of minimizing the total cost or maximizing the whole productivity.

Froth Washing in Flotation
Froth flotation is a mineral processing technique that is popular when processing low-grade ores. It involves introducing chemically treated, finely ground ore in the form of a slurry into a flotation cell where the air is also added in the form of bubbles. The cell is agitated resulting in the air bubbles rising to the top and creating a froth, as bubbles rise, hydrophilic particles attach to the rising bubbles creating a froth which is collected in the weir or using launders for further treatment. The froth is washed using various froth-washing techniques to reduce entrainment and improve the grade of the froth. Froth washing can be achieved using froth washing jets or froth washing trays, this can be achieved internally/externally with regards to the position in the froth layer.
