RESEARCH GROUP: Paolo Berry, Roberto Bruno, Stefano Bonduà, Annalisa Bandini, Sara Focaccia KEYWORDS: ore deposit, geostatistics, numerical model, mining and quarrying, reclamation

The mineral raw materials are the basis of any process of economic development of man. The team deals with the characterization, modelling, selection and exploitation of mineral deposits and deposits of industrial materials.

Specific topics are the spatial variability studies and modelling of useful substances and of pet- rophysical properties of the materials, the opti- mization of their sampling, the selection of the exploitable resources, technically and economi- cally. Geostatistics is one of the major theoret- ical frameworks adopted; estimated and sim- ulated models are typical tools used. The best international geostatistical software is available (ISATIS, …) besides its own library.

In the sector of ornamental stone characteriza- tion, in the last 15 years the team coordinated or was partner of several international projects supported by the European Union (COSS; OS- NET; FARO). In this field, an original technol- ogy was developed, and then patented, for the characterization of ornamental stone by image analysis. An advanced image processing of the surface of slabs and tiles can achieve goals re- lated to aesthetics, such as quality certification, certification of origin, the automatic selection of different products and the degradation analysis. The research topics in the sector of exploitation of raw materials are mainly focused on:

• planning and design of mining activities, at gion- al and local scale;

• processes of selecting the most appropriate meth- ods for mining;

• environmental impact assessment and monitor- ing of surface and underground mining;

• safety in underground, namely for methane emissions during stopes and excavations;

• reclamation aspects in planning and design; • reclamation modelling and requalification proj- ects;

• rehabilitation of abandoned mines and quarries. Design software for ventilation networks, blast- ing, environmental control for open pit mining,

was developed. In situ tests are done by ad- vanced technologies (laser scanner, satellite im- ages) and environmental controls are carried out (seismicity induced by blasting, overpressure).
