Linee di ricerca

  • Mechanical characterisation, at different scales (geometrical and time-dependent), of rocks: the rational approach to problems of interaction rock-explosive, rock-tool, rock-crusher and so on, has been developed by considering issues of the conceptual connection between the petrographic and the geo-mechanical description of rocks. From these studies, both the usefulness and the possibility of a micro-mechanical description come out, on the basis of the statistical analysis of hardness tests and, in particular, of micro-hardness tests, in parallel to a conventional description. The inadequacy of the conventional geotechnical description to foresee the rock behaviour in some technological processes involving the production of thin fragments (grinding, cutting by micro-tools and so on) is highlighted; the opportunities of a micro-mechanical analysis and a small scale geostatistical description are pointed out; the effects of the load application on the mechanical behaviour of rocks (fatigue phenomena) are also taken into account.
  • Mechanical cutting of rocks: numerous predictive models are present to determine the parameters that affect the mechanised excavation through tools, based on the characteristics of the rock mass and those of the equipment used. Although widely used, in many cases, these models have limitations in their application and, consequently, in predicting the machine parameters for different lithological conditions. For these reasons, the current trend is to carry out experiments of rock excavation with tools at a real scale. In this regard, a Linear Cutting Machine (LCM) has recently been designed and implemented, in collaboration with other colleagues of the DIATI, to acquire influential parameters on the excavation with disc tools directly, and to evaluate possible configurations of the most suitable machine.
  • Rational use of explosives in different conditions; in this field, many experimental researches are under development, aimed to the control of the evolution of the excavation geometry (both open pit and underground and, in this last context, both in tunnelling and in production techniques, i.e. "rooms and pillars "and" sublevel stoping"); the same goal is pursued in the field of dimension stones: refinement of the dynamic splitting and techniques of pre-splitting and smooth-blasting are being tested in many Italian quarry-sites, also paying attention to the problems of environmental control (vibration, fly-rocks, dust, noise, etc..)
  • Vibrations induced by blasting, especially in the proximity of sensitive structures, were studied extensively to focus on the environmental impacts of exploitation. The best conditions for obtaining the desired rock fragmentation (respecting the required daily production) were also defined.
