This week two of our teams (UPM & Sigma) visited DigiEcoQuarry’s pilot site near Madrid, Valdilecha’s quarry from Cemex, to continue with their work regarding Work Package 4 Stockpile Volume Calculation & Work Package as well as Mechanical Failure Detection.

During the visit, the different experts in these teams measured and analyzed the levels of sound at several places like the conveyor belts, the screens, and the crushers to study and identify acoustic anomalies that might lead to early mechanical failure detection in these areas through the survey of both vibration and sound. Thanks to this field of study, we will be able to determine each machinery based on these two variables and perform a diagnosis in real time.

On the other hand, some members of the teams tested other very useful and important applications of their work using images instead of sound. The goal is to be able to calculate the stockpile volume using a smartphone by recording a video around the pile thanks to software developed for this matter. After recording the video, the software offers a 3D reconstruction, 3D segmented piles, and an estimation of the volume with a margin error of less than 3%. A drone was also used to record images of the piles.

DigiEcoQuarry’s ambition is to tap the full potential of digital quarries through a significant breakthrough in process digitalisation and automation capabilities for the aggregates sector. DigiEcoQuarry, a project funded by the European Commission and led by ANEFA, aims to design, develop, and validate in 5 pilot environments an Innovative Quarrying System (IQS) comprising sensors, processes, tools, and methods for data capture, processing, and sharing to provide integrated digitalised, automatic, and real-time process control for aggregates quarries.
