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.

Artisanal and Small-Scale Gold Mining
The aim of this work is to explain the concepts of sustainability with respect to small artisanal gold mining. For this, a qualitative approach with a descriptive scope was used, for which the bibliographic review technique was conducted. In this sense, articles, theses, books and institutional documents, and any contribution related to the research topic were taken into consideration. Likewise, this documentation contributed to the delimiting aspects that allowed a contrast between the proposed definitions and small artisanal mining in the Northeast Antioquia region in Colombia. Based on the reviewed sources, different needs were recognized in artisanal small-scale gold mining in Northeast Antioquia that still need action. In conclusion, through the exposition of sustainability theories, three common factors were identified within the various positions that were raised—the environmental, economic, and sociocultural dimensions.

Beneficiation Methods of Borate Minerals
The modern boron applications have adsorbed the mineral processors’ attention to improve typical boron mineral’s (BM) beneficiation methods. In this regard, dry treatment and pretreatment processes—such as magnetic separation and calcination as environmentally friendly methods, due to their minimal or zero adverse effect on the environment—need more consideration. Over the years, anionic flotation has become the main technique for beneficiation of friable BMs; however, there is a gap in the investigation of cationic flotation separation since BMs’ surface negatively charges in a wide pH range. At present, enriching BMs’ flotation via surface modification is taking center stage, which can also be considered for reprocessing long-forgotten BM tailings.

Chemical Composition of Sulfide Copper in Chile
Copper is a metal that presents several industrial applications due to its attractive properties, such as electrical conductivity, thermal conductibility, and ductility. It is mainly used in electrical wiring, industrial machinery, plastic electroplating, printed wiring boards, zinc die casting, automotive bumpers, and rotogravure rolls. Copper is especially important in the semiconductor industry because, in general, the connections on chips are made of this metal due to its low electrical resistance, good mechanical properties, and high corrosion resistance. In addition to this, copper can form alloys with various elements.

Construction of Arch Structure Model
The application of the arch structure model focuses on the prediction and prevention of mining pressure and surface subsidence, and there are relatively few means to actively regulate overburden arch.

Deep Sea Mining
As land-based mining industries face increasing complexities, e.g., diminishing return on investments, environmental degradation, and geopolitical tensions, governments are searching for alternatives. Following decades of anticipation, technological innovation, and exploration, deep seabed mining (DSM) in the oceans has, according to the mining industry and other proponents, moved closer to implementation. The DSM industry is currently waiting for international regulations that will guide future exploitation.

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.

Digital Twin Technology in Data Center Simulations
Mining activities often deem mine sites as temporary, leading to their eventual reclamation, rehabilitation, or abandonment. The abandoned mine sites can be reimagined as strategic assets, thus providing economic benefits while adhering to critical data center infrastructure standards.

Dispatch Optimization Model for Haulage Equipment between Stopes
The working environment of underground mines is complicated, making it difficult to construct an underground mine production plan. In response to the requirements for the preparation of a short-term production plan for underground mines, an optimization model for short-term resource planning was constructed, with the goal of maximizing the total revenue during the planning period.
