Chile is one of the main copper producers in world. It located a geographical area where mega-earthquakes occur and this fact, together with development larger higher sand tailings dams (with some facilities currently under having final heights excess 250 m), requires that careful attention be paid to safety security these facilities. In paper, failure mechanisms have generated incidents different magnitude involving loss human life, significant environmental damage, economic losses are...
The Chilean copper mining industry generates large amounts of waste rock materials. These structures must be designed, operated, and closed considering their physical stability. Although these generally do not present stability problems, superficial failures may occur, where material is subjected to low confining pressures. identification the internal friction angle, necessary for calculations, based on characterisation materials under high This assumption representative loading conditions...
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 study critical variables TD that allow estimating different potential failure mechanisms (PFM): seismic liquefaction, slope instability, static overtopping, and piping, which may occur in type storage facilities a seismically active country such as Chile. Thus, article proposes...

Chile is one of the major producers copper in world, and as such responsible for 1.7 million tons tailings per day. While most commonly used deposit to store this type mining waste historically sand dams, industry has over last two decades been inclined toward thickened dams (TTD) because their advantages water resource recovery, lower environmental impact, better physical chemical stability conventional deposits. Within geotechnical area, key requirement TDD, need monitor moisture content...
This article presents a method to detect and segment mine waste deposits, specifically rock dumps leaching wasted dumps, in Sentinel-2 satellite imagery using artificial intelligence. challenging task has important implications for mining companies regulators like the National Geology Mining Service Chile. Challenges include limited knowledge of deposit numbers, as well logistical technical difficulties conducting inspections surveying physical stability parameters. The proposed combines...

Copper mining produces significant amounts of associate waste, leading to the construction huge waste dumps in highly seismic zone Andes Mountains. To analyze stability these deposits, it is necessary characterize mechanical properties materials laboratory, which quite difficult due large size particles composing structures. In this study, global mine analyzed by means discrete element simulations. Three analogues upscaled particle distributions were generated from original PSD. The dump...
