Optimizing of regime parameters in the rock disintegration

The contribution describes a concept of the evaluation of rock disintegration process using the energetic theory and an optimization of rock disintegration process depending on input parameters, i.e. the thrust force and the torque. The interaction of the tool and the rock causes deformations, mechanical oscillations, etc. The Department of destructional and constructional geotechnics of the Institute of Geotechnics SAS investigates the vibrations from both the quantitative and qualitative point of view. The evaluation of disintegration processes improves the energy distribution and the efficiency of the mechanical rock disintegration. The paper evaluates the initial measurements at the rock disintegration by drilling. The contribution is a form of a profile and joins the optimization of rock disintegration based on input parameters with the optimization of a width of the drilling tool segment. The vibration signal as a carrier of the information on the process enables to improve the optimization with further parameters of rock disintegration, such as the rock type, tool and the tool wear.
