Chile’s mining industry, a global leader in copper production, faces challenges due to increasing volumes of mining waste, particularly Waste Rock Dumps (WRD) and LeachingWaste Dumps (LWD). The National Service of Geology and Mining (SERNAGEOMIN) requires assessment of the physical stability (PS) of these facilities, but current methods are hindere...
MineWaste Storage Facilities (MWSFs) in Chile present substantial environmental and safety risks due to their extensive scale and the hazardous nature of their contents. This study proposes an automated detection approach that integrates Sentinel-2 satellite imagery with advanced deep learning models to address these critical issues. A central cont...
In the global mining industry, periodic monitoring of large Mining Waste Deposits (MWDs) is essential. This paper presents an innovative approach leveraging advanced artificial intelligence techniques combined with high-resolution Sentinel satellite imagery to accurately geolocate MWDs in Chile.

In this research, we address the problem of evaluating physical stability (PS) to close tailings dams (TD) from medium-sized Chilean mining using artificial intelligence (AI) algorithms. The PS can be analyzed through the study of critical variables of the TD that allow estimating different potential failure mechanisms (PFM): seismic liquefaction,...

Sand tailings dams have historically been the most commonly used technology for tailings storage in Chile. Although engineering advances have resulted in the construction of approximately 250-m-high facilities, some operational challenges still remain, including compaction control. Control is currently performed at a few control points in a dam emb...
Complex industrial problems coupled with the availability of a more robust computing infrastructure present many challenges and opportunities for machine learning (ML) in the construction industry. This paper reviews the ML techniques applied to the construction industry, mainly to identify areas of application and future projection in this industr...
Over the course of little more than a century, several large-magnitude earthquakes have struck Central Chile. In the area within the Marga-Marga basin in the city of Viña del Mar, notable damage to buildings suggests the occurrence of local seismic site effects. While seismic microzonation studies have attempted to explain such effects, the geotech...
La actividad minera ha sido practicada en Chile desde hace varios siglos, inicialmente por parte de los aborígenes, posteriormente los conquistadores y en la actualidad activamente, explotando minerales no metálicos y metálicos, lo que ha contribuido al progreso del país. Sin embargo, esta actividad constituye un potencial riesgo de afectación para...
Proper tailings storage facilities (TSF) management can be done by monitoring various variables, such as moisture, which influences at physical and chemical stability phenomena. Nowadays, there are no continuous moisture controls due to the dangers associated with taking samples in tailings, generally in low-density states, making access difficult....
The application of continuous metaheuristic algorithms to combinatorial problems is an area of interest at the engineering level. This interest is related to the fact that many of the problems that are addressed at the industrial level are of the combinatorial type and a not lesser subset of these are of the NP-hard type. In this article, we propos...
At the business level, there are a large number of combinatorial problems. A subset of these is NP-hard type. The study of algorithms that address this type of problem is of great interest. On the other hand, there are a large number of metaheuristic algorithms that naturally work in continuous spaces. Adapting the latter to solve combinatorial pro...
In the fields of engineering and science, there are many combinatorial optimization problems. Many of these problems are NP-hard problems, which are difficult to solve with complete techniques. Therefore, the design of binary algorithms based on swarm intelligence continuous metaheuristics is an area of interest in operations research. In this arti...
When exploration depth is shallow or site access is limited, a dynamic lightweight penetrometer is an attractive alternative to large penetrometers. Cone resistance, regardless of the penetration test, is influenced strongly by soil conditions: dry unit weight, overburden stress and water content of the surrounding soil, and fines content. This stu...
Empirical evidence has shown that particle breakage affects the mechanical behaviour of granular materials. The source of this mechanism takes place at the particle scale, and the main consequence on the macromechanical behaviour is increasing compressibility. Due to the inverse correlation between particle size and particle crushing strength, coar...
Chile is one of the major producers of copper in the world, and as such is responsible for 1.7 million tons of tailings per day. While the most commonly used deposit to store this type of mining waste is historically tailings sand dams, the mining industry has over the last two decades been inclined toward thickened tailings dams (TTD) because of t...
Copper mining produces significant amounts of associate waste, leading to the construction of huge mining waste dumps in the highly seismic zone of the Andes Mountains. To analyze the seismic stability of these deposits, it is necessary to characterize the mechanical properties of these materials in laboratory, which is quite difficult due to the l...

Optimization at the industry level is a fundamental area since it allows reducing costs and being more sustainable. Many of these problems are combinatorial and NP-hard. On the other hand, swarm intelligence metaheuristics have been able to successfully address these types of problems, however, many of these techniques work in searching continuous...

Tailings storages facilities are constructed over a period of years or even decades where their operation has a direct impact on the extraction and milling of minerals, and therefore, in the global mining business. To optimize the operation of the facilities, as well as to evaluate their physical and chemical stability, it is necessary to continuou...
In geotechnical engineering penetrometers are used to estimate in situ soil properties. The most influential variables in penetration resistance, are soil density and confinement stress. Light penetrometers are an economic, fast and versatile alternative, in contrast to traditional penetrometers, such as standard penetration test (SPT) or cone pene...
The effects of underground blasting on stress wave propagation, blast response and generation of pore water pressures in cemented paste backfilled (CPB) stopes is researched in this study. Through LS-DYNA the effects of sequencing of detonation and number and blasthole proximity on the total and residual pore pressures exerted in the fill was explo...
In Chile, sand tailings dams represent the most common deposits of mining residues. These structures present a potential risk in terms of mechanical instability due to their potential susceptibility to seismic liquefaction. In order to manage these risks, it is necessary to take a probabilistic approach, thus accounting for inherent variability of...
Chile is one of the main copper producers in the world. It is located in a geographical area where mega-earthquakes occur and this fact, together with the development of larger and higher sand tailings dams (with some facilities currently under development having final heights in excess of 250 m), requires that careful attention be paid to the safe...
PANDA technology is currently being used to regulate compaction and provide in-depth quality control for tailings deposits in Chile, owing principally to its rapid, non-destructive, portable, easy-to-use and environmentally sustainable testing which is based on normalised methods and able to produce immediate results. In the last few years research...

Thus, tree roots provide a reinforcement system that depends on its structure and distribution. This article presents a research applied to a natural slope in Reñaca-Chile, and the objective is...

Dams are often used for storing mine tailings. These structures present failure mechanisms that can lead to major risks for
surrounding populations. In view to managing these risks, it is necessary to take a probabilistic approach in predicting their
behaviour. The application of such approaches is limited by the difficulty of obtaining experimenta...

Although the mining residues in a global way can be classified in a single class of granular material, a set of causes lead to a variability of the geotechnical characteristics of the material and of the internal structure of the dams constituted from these. Consequently, to adopt a hypothesis of homogeneity to estimate the mechanical stability of...
