Abstract
Climate change (CC) affects the environment. This requires from geotechnology to plan its interactions in the geosphere in a way that preserves the existing equilibrium. The program aims to improve geotechnological processes related to the reduction of environmental footprint in the production of energy, large infrastructure projects and mitigation of the effects of climate change on the environment. The ecological footprint of coal is lower if it achieves a higher calorific value, it is homogeneous and has a lower admixture content. Therefore, longwall coal mining methods need to be introduced, which result in the formation of rock burst, which in certain cases prevent the mining processes. Our opinion is that the correct supports and measures for real-time relieving of elastically over load rocks help to reduce this problem. Many environmentally hazardous wastes are stored in large underground spaces, built in unbound sediments and semi-rocks with low hydraulic permeability. Therefore, in such cases it is necessary to use geotechnical modeling for nonassociative materials, to extend the solutions of associative on nonassociative. Geothermal energy is among environmentally friendly sources of energy, for the use of low enthalpy systems that are suitable for heating, nor need deep, while paying particular attention to the effects of temperature changes on the physical and mechanical properties of the soil. For larger heating surfaces, it is necessary to drill into larger depths. In order to achieve deeper depths, we will continue to develop in the field of drilling bits and materials, where we will continue their inspection on electronic microscopes and by studying the effects of different drilling modes, rock properties and bits properties. Electricity generated from hydroelectric plants, with the correct approach, has a small ecological footprint. Using optical cables and mathematical modeling, we will study the influence of accumulations on the groundwater regime. In the field of geotechnical construction (GS) we will investigate the influence of various geomechanical models on the limit state of load capacity and the limit state of use of GS. We will make a comparison between analytical and numerical models of GC. The purpose of these research is to develop new recommendations for the analysis of GC, for practice use. In order to explore the competitive advantages of different GKs, we will use multi-parametric integer nonlinear programming (MINLP) and the Genetic Algorithm (GA). Analyzes, assessments and decisions will be made in the planning of the GK, taking into account uncertainties and consequences. By using the water balance model GROWA-SI, UAV and lithological data, we will try to determine the amount of rainfall that causes surface instability.
Significance for science
The smaller ecological footprint of coal in the production of electricity is achieved by the use of coal with a high calorific value, which must be accessible in the required quantities. This means that in the case of coal mining, where excavation is carried out underground, coal mining should be carried out with the longest longwall. In the conditions of sedimentary rocks and semi-rocks, in the case of wide longwalls methods, the accumulation of elastic energy in load-bearing pillars occurs, which, when exceeding the strength, abruptly abate, which is seen as a strong shaking of the soil, which usually damages the mining facilities and poses a mortal danger to miners near the event stroke. Members of the research group, with the cooperation of the coal miners' experts, came to the conclusion that the reduction of the rock streets should be ensured by the prompt release of the elastic energy in the load-pillars. We believe that this finding is very important, not only for the coal industry, but for the whole underground construction in similar rocks. With further work, we will try to find out which supports are better for reducing rock burst and which additional release methods are more appropriate and which will undoubtedly make progress in underground coal extraction in unbound sedimentary rocks and semi-rocks. For the exploitation of medium and high enthalpies of geothermal energy it is necessary to achieve large depths, and the achievement of these requires drilling. In doing so, we will investigate the damage caused by drilling tools with an electronic microscope and other special laboratory techniques. Based on these findings, we will produce diagrams of the mechanical properties of rocks, drilling bit properties and drilling parameters, which will show how different parameters influence the optimal choice of drilling bits. Determination of the impact of hydroelectric power on groundwater is crucial in times of climate change. Clogging of the river banks is the factor that strongly influences the connection between the underground and surface water. The main problem is the measurement of infiltration, which is directly related to the clogging of the river banks. In our program, we predict the measurement of infiltration through measurements of temperature changes in the river banks, in which optical fibers already in place are susceptible to change in ambient temperature. In geothermal energy, geothermal constructions have a dual role, i.e. ensure adequate structural load and thermal energy. The design of such structures is demanding, because the cyclical changes in temperature change the properties of the underlying floors, and at the same time there are additional stresses in the construction due to the temperature expansion of the elements. The construction of geothermal structures is now smaller because the designers do not have the right tools for dimensioning. The change in soil properties will be analyzed on the basis of experimental field and laboratory tests. In addition to the assessment of the heat exchange between geothermal foundations and the surrounding media (soil), we will also investigate the mechanical response of the soil to the change in temperature between energy structures and the surrounding media. The impact of the use of geothermal energy on the environment will be analyzed. We will draw up instructions on the structural reliability of geothermal structures, which will take into account technical, economic and environmental aspects. In the field of soil improvement, as a measure to the effects of climate change, the emphasis will be on the experimental study of the stress-strain relationship in embedded geosynthetics and different earths. The results of experimental research will enable a realistic modeling of the reliability of structures made of reinforced soils. Geomechanical models for the analysis of the following reinforced structures will be produced: bridge supports, gravel slopes, emban
Significance for the country
The natural features of Slovenia, its location and its geological and hydrogeological soil
structure allows it to achieve a greater potential in the use of shallow and deep geothermal energy. Development of instructions on the structural reliability of geothermal structures will significantly contribute to the design of geothermal structures. Geotechnical models will allow for more realistic and optimal solutions to practical problems, resulting in a more rational and more reliable construction of particularly demanding geotechnical structures. The use of design models in engineering practice will be demonstrated. By developing and using various optimization techniques, we can significantly reduce the costs and consumption of materials in the construction of geotechnical facilities, while at the same time increasing the productivity and competitiveness of construction companies.
The desire for energy self-sufficiency it directing us to domestic energy sources while at the same time searching for the smallest carbon footprint. The proposed research in the field of geotechnology and mining interferes with the direct acquisition of energy for the heating of buildings and green houses (deep drilling and deep geothermal research with mathematical modeling of heat transfer), solving the ecological impacts of hydro power plants with small carbon footprint on groundwater and flood safety, the production of large underground transport routes, which will greatly reduce the carbon footprint in transport and eliminate the problem of storage of low and intermediate radioactive waste in Slovenia (silos).
