Research subject for a potential FP6 project

Project is focused on the scientific and technical analysis of the influence of selected technical process (tunnelling using an on-line monitoring) that has an unfavourable impact on the working environment and country ecology. The technical in-situ process of tunnelling in Slovakia will be monitored and evaluated using a new model approach developed at the Institute of Geotechnics of the Slovak Academy of Sciences in Kosice with favourable scientific response of geotechnical institutes and organizations worldwide. For a machine driving of the transport tunnels there has been evaluated a monitoring and optimising system, which can guarantee an effective use of the energy needed for the rock disintegration and a significant increase of the lifetime of disintegrating tools. This system also enables a prediction of tectonic failures in the rock mass, continuous identification of the rock mass properties changes and monitoring of the fibrogene air-borne dusts resulting from the driving process. The technological parameters of tunnelling in tested rock will be evaluated on the basis of physical-technical analysis of the disintegration process, using the latest statistical methods (Fourier transformation, fuzzy simulation, fractal mathematics, etc.). The negative influence on the environment (noisiness, dustiness, toxic emissions, i.e. CH₄, NO_x, CO_x, etc.) will be consequently predicted, as well as the devastation effect on the country ecology. The advanced on-line systems of the indication of harmful factors and toxic components of emissions will be used to evaluate factors of internal and external environment. In addition to these main factors of unfavourable effect on a human, the actual concentration of the greenhouse gases (CH₄, CO₂, organic toxic components) will be indicated in and near the tunnel, in order to create a database information system using a systematic and scientifically adequate procedure for a globalisation of negative effects of technical processes in Europe, in accordance with the Kyoto protocol.
