Salt caverns are used for over 70 years to store power sources and dispose of industrial wastes.The design cavern shape dimensions is still considered as a difficult engineering problem despite progress in geotechnical, construction exploration methods.The rational depends on mechanical parameters rock salt nonsalt rocks, stability conditions, safety requirements stored material.However, most these factors related geological like depth location, the structure deposit, lithology interlayers,...
Salt caverns are an attractive solution to the growing energy demand in view of their large storage capacity, safety operation and long time. The designing process salt is still considered a complex issue despite progress geotechnical, construction exploration methods. Finding optimal shape dimensions cavern given geological conditions difficult engineering problem stability requirements. In this paper, typical shapes (cylindrical, enlarged top, bottom), with each three variants differing by...
This paper presents a complex study of anhydrite interbeds influence on the cavern stability in Mechelinki salt deposit.The impact shape and stress concentrations were also considered.The analysis was based 3D numerical modelling.Numerical simulations performed with use Finite Difference Method (FDM) FLAC3D v. 6.00 software.The model cuboidal following dimensions: length 1400, width height 1400 m, comprised part deposit.Three (K-6, K-8, K-9) caverns projected inside this model.The mesh...
Shale, a fine-grained sedimentary rock, is composed of highly compacted clay particles, nanometric porosity and silt-sized particles other minerals. In this paper, combined use X-Ray micro-CT nanoindentation tests proposed for the qualitative quantitative characterization material. The individual methods are utilized at different scales observation: nano micro level while X-ray microtomography meso scale. For purpose mechanical morphology evaluation, grid measurements carried out resulting...
Abstract Effective planning of the cavern field involves determining optimal pillar width between caverns and feasible number based on geological mining conditions. The proper design is crucial to ensure stability rational utilization rock salt deposit. pillars a complex problem influenced by various factors, including creep, changes in pressure during operational cycles, mechanical parameters, failure criteria salt. To address this problem, relation widths evaluated. evaluation following...
Abstract Stability of mining openings requires consideration a number factors, such as: geological structure, the geometry underground workings, mechanical properties rock mass, changes in stress caused by influence neighbouring workings. Long-term prediction and estimation workings state can be analysed with use numerical methods. Application 3D modelling stability complex was described example Crystal Caves Wieliczka Salt Mine. Preservation reserve is particularly important view their...
The extraction of the Bełchatów lignite deposit located in vicinity Dębina salt dome requires careful planning that considers influence mining projects on slope and stability conditions. instability problem is directly related to horizontal vertical displacement, as well complex geological These conditions are very unique with regard co-occurrence deposits same area, large scale pit wall slope. Thus, predicting rock mass behavior ensuring safety operations important issues. presented...
Abstract Located in central Poland, the Kłodawa salt dome is 26 km long and about 2 wide. Exploitation of started 1956, currently rock extraction carried out 7 mining fields 12 levels at depth from 322 to 625 meters below sea level (m.b.s.l.). It planned maintain activity till 2052 extend deeper levels. The characterised by complex geological structure resulted halokinetic tectonic processes. Projection 3D numerical analysis took into account following factors: mine working distribution...
Abstract The geological structure of the Bełchatów area is very complicated as a result tectonic and sedimentation processes. long-term exploitation field influenced development horizontal displacements. variety factors that have impact on western slope stability conditions, forced necessity complex geotechnical monitoring. monitoring was carried out with use inclinometers. From 2005 to 2013 fourteen inclinometers were installed, however, currently seven them are in operation. present...
The paper presents the attempt to find a correlation between content of impurities and mechanical parameters rock salt from LGOM. Research was carried out in three steps: uniaxial compressive strength tests, determination insoluble minerals (impurities), observations under microscope Raman microspectroscopy. research results reveal that which is characterized by low (0.13–2.11% wt.) shows no properties impurities. However, it found depend on both distribution halite crystals presence fluid...
Microhardness tests were carried out on single halite crystals. They conducted the (001) surface, with indenter set in two directions: parallel to face (010); and (110) face. The crystals represent salt formations of different ages (Devonian, Zechstein, Badenian), depths (from 1835.5 195 m) intensities tectonic disturbance (horizontally stratified, dome, strongly folded). measurement results revealed specific features analysed. Firstly, data obtained show microhardness anisotropy Moreover,...
