In MARINI use-case Dig_IT Predictive Operation aims to address waste reduction and reduce unpredicted downtime contributing to overall productivity optimisation, while Predictive maintenance agents for critical equipment (chainsaw, diamond wire, multi-blade gangsaw) will lead to significant maintenance cost reduction and planned downtime reduction. Dig_IT EHS online monitoring in combination with Smart Garment (SG) wearables will provide cross-validation for workplace particle monitoring of air and gases to assess underground air quality and improve safety in the workplace and a Digital Twin for fluid dynamics will provide a real time risk map. The SG will also provide monitoring of biometrics, noise and, OHSE parameters that will be interpreted into intelligent outputs regarding situational awareness through the Intelligent Toolbox for OHSE. All related processes will be assessed and optimised through the Dig_IT Smart Scheduling tool Dig_IT components will be visualised through the Dig_IT Business Intelligence Decision Support System and all systems will be integrated in Dig_IT IIoT platform.
From its origins Marini Marmi extract and process its stones from its own quarries which are located in northern Italy, on the right bank of Lake Iseo (Lombardy region). In particular the Company is specialized to produce stones to size, using its exclusive stones like Ceppo di Gré and Nuvolato di Gré. Ceppo di Gré (on the right) is a monogenic dolomitic breccia. Quaternary – Pleistocene 600-300.000 years. Nuvolato di Gré (on the left) is a sedimentary, carbonatic, veined and breccia textured. Jurassic 220-240 millions of years. The Marini Marmi’s goal is to supply high quality products and in order to do this a strict quality control on the production chain is planned.

The use case in La Parrilla is primarily focusing on the Dig _IT Geotechnical DT component and related DSS of the Dig_IT IIoTp to: i) optimise the geotechnical monitoring system; ii) improve mine planning with the deployment of 3D geological mapping; iii) calculate stability of the pit slopes and spoil heaps. In La Parrilla mine Subterra will use the results of modelling to give feedback to geometrical control aiming to establish different thresholds to predict ground and structure geomechanical behaviour via aerial and terrestrial monitoring. SUBTERRA will monitor the main parameters determining slope behaviour, planning to install several sensors in rock faces and dam walls such as: inclinometers, piezometers, total pressure cells also performing surface displacement monitoring using aerial and terrestrial methods. LIBRA will provide the framework for decision making based on La Parrilla and SUBTERRA requirements. All systems will be integrated in the Dig_IT IIoT platform. La Parrilla business is focused on the production, development and exploration of tungsten and tin in Spain and Portugal. The strong point of La Parrilla business is the strategic location (7 km from Seville/ Madrid highway) which offers some important advantages like: access to quality water supply, facilities and on-site laboratory operational and connection to Spanish power grid. Regarding the mining operation La Parrilla can rely on standard drill and blast, load and haul open pit mining, easy access to mining area trough limited modification of existing infrastructure and short haul distance to RoM pad.

Through Dig_IT, Titania will focus on increased digitalisation of environmental monitoring, mining operations and planning, including providing an information flow for the local community regarding the environmental compliance of their operations by integrating Environmental Compliance monitoring to also facilitate communication with local stakeholders. Dig_IT will develop and test on-line EHS measurements at the Titania site, focusing on an automated system for water discharge analysis and management EHS measurements will be cross validated with geo-located Smart Garment (SG) measurements. Dig_IT will also employ related sustainability methods (e.g., LCA) to assess the overall environmental performance of the mine. Dig_IT geotechnical DT of the mine will simplify stability monitoring of the mine to improve associated risk management and decision making. Remote sensing and in-house operated drone flights will significantly contribute to building a nearly real time geotechnical model API for Dig_IT integrated DSS component that will advance into a real time DT using ROMs. Also, Dig_IT will assess the feasibility and potential of implementing Predictive Operation and Maintenance, to reduce operational risk, enhance equipment and machinery utilization and increase efficiency of the mine by optimizing the production pace and reducing downtime of critical assets. Through Dig_IT Smart Scheduling component a set of related parameters regarding mine operation (i.e. energy water waste, routes) will be analysed and integrated into the mine DSS improving overall mine performance. All systems will be integrated in the Dig_IT IIoT platform. Founded in 1902 by a metallurgist developing a use for ilmenite, which is processed into titanium dioxide (TiO2) to whiten paint, today the core business is represented by the process which consist in the transformation of the ilmenite norite (18%TiO2) into Ilmenite concentrate (44% TiO2) and its placing on the market.

Through Dig_IT, TAPO will focus on increased digitalisation of occupational environmental monitoring and health and safety (OHSE) monitoring, providing an information flow for the local community regarding the environmental compliance of their operations by integrating Environmental Compliance monitoring to facilitate communication with local stakeholders. Dig_IT will develop and test on-line EHS measurements Dig_IT methodology for online EHS measurements and Dig_IT Sustainability Compliance Labelling (SCL) will be envisioned online and will be made available to cover bespoke needs for insights/information of different audiences such as: a) the permitting authorities, and b) the local community. SCL will ensure trustworthy resource monitoring and is planned to encourage the participation of the local stakeholders within the Ethereum (public) Blockchain of Dig_IT.

Through Dig_IT, TAPO aspires to address their needs in predictive operation, predictive maintenance, optimal scheduling, operations management optimization, energy consumption reduction through new technologies and onstream data analytics. Digitization of the Sotkamo Silver underground mine environment will permit to achieve the EHS methodologies to increase the workers safety. These guidelines will be carried out with real time measurements of different parameters, such as temperature variations, rock dust, air quality (NOx or exhaust gases), noise, vibration, etc, or with technologies to support human vision and hearing in charging and other skills in loading and transport or with application of technologies to increase hygiene at work.
