The aims of the programme were to research into the domain of geotechnology and mining, in areas such as: characterisation of dispersion systems; research into rock mechanics and geotechnical engineering, focused on geotechnical structures, technological procedures for construction of underground facilities, and extraction of raw materials or development of excavation methods and technology, e.g. ventilation, construction of dump sites, etc. The main activities of the research programme included the characterisation of a multiphase system of calcium carbonate / calcium hydrogen carbonate, i.e. in the presence/absence of magnetic field. The research aimed at introducing a magnetohydrodynamic method for processing or cleaning of technological feed waters. The focus of our research was on the measurement of zeta potential during the phase of calcium carbonate precipitation, and on determination of the portion of crystal forms thus precipitated (i.e. calcite, waterite, aragonite). The experimental work was carried out primarily in pure systems, but also in the presence of known amounts of other ions, which - in the presence of magnetic field - had a favourable effect on the precipitation of calcium carbonate in aragonite crystal form. The aragonite form of precipitated calcium carbonate is much more favourable in terms of formation of pipeline deposits. On the other hand, the precipitation of calcium carbonate in the form of calcite can be very problematical. The research has confirmed the previous findings regarding the favourite form of aragonite in the presence of magnetic field, and also in the presence of other ions - especially heavy metals, such as copper, zinc, iron. There is still difference of opinions in the world as to the prevailing mechanism. In our experimental work, we managed to increase the repeatability of the results, but we could not completely eliminate the dissipation of the results. The effect of magnetic field is still complex enough, so there is no satisfactory, world-level interpretation of the reasons for formation of various crystal forms of calcium carbonate. The programme was successfully implemented in the domain of scientific behavioural analysis of tall supporting structures built in low-capacity, geologically sensitive rocks, as well as in the domain of scientific studies within the framework of a draft design regarding the possibilities of constructing an underground dump site for low- and medium-level radioactive waste. In the domain of mining, research into the analysis of destructive processes during coal excavation underneath thin insulation layers or underneath lake surfaces was conducted. The application of the research programme was extended to individual fields of geotechnology, with particular stress on the possibilities of constructing long underground facilities (e.g. tunnels) by the method of cutting out the complete excavation profile in various layers of rock or soil.
