The main purpose of this paper was to study discontinuous and folded dislocations in the tuffs of the Teresvinsk bed of the Lower Neogene and to reconstruct of paleostress fields in the Tyachevets River basin of the Transcarpathian Trough. Methods. Structural-geological methods of field research and methods of tectonophysical field research are used in the work. Processing of field data was carried out with the construction of a structural-geological scheme of the research area. «Win-Tensor» software was used to process the data and to determine the paleostress fields. Results. Numerous folded and discontinuous dislocations, their interrelationships and paragenesis are found in tuff outcrops on the northern outskirts of Lazy village, Tyachiv District of, Zakarpattia («Chorna Voda» area). Tectonophysical studies of tectonic cracks and rupture faults were conducted. Were installed paleostress fields of different ages and kinematic types.The shear field is dominate among these fields and is the youngest in terms of age. The main region fault of the northwest-striking was studied. It has been established that this fault is a strike-slip fault. The second fault of the same direction cuts and displaces the northeast-trending synclinal fold. Scientific novelty. The age relationships of the systems of discontinuous and folded dislocations in the zone of influence of the large northwest-striking fault have been established for the first time. This fault formed and developed as a dextral strike.Several stages of activation of discontinuous structures and several types of different paleostress fields are established.The shear field of paleostresses predominates and has the youngest age Practical significance. It was established that numerous dislocations and their multi-stage activation over time contributed to the formation of hydrogen sulfide mineral waters, which are located in the zone of the main fault. The obtained research results clarify the history of the tectonic development of the Transcarpathian depression and indicate the presence of several stages of tectonic activations in the Neogene. Key words: tuffs, discontinuous dislocations, dextral shear, synclinal fold, paleostress.","PeriodicalId":430946,"journal":{"name":"SCIENTIFIC PAPERS OF DONNTU Series: “The Mining and Geology”","volume":"301 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134145650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Investigation of the conditions for the occurrence of coal and gas outbursts from a geochemical point of view. Methodology. The paper examines and analyses the results of determining bituminous and hydrogen indices using the Rock-Eval thermolytic analysis method on safe and dangerous areas of coal seams in terms of coal and gas outbursts. Results. It was established that on safe mining seams, coal samples are within the oil window, where microcracks in the coal mass may still contain films of sorbed bituminous components (liquid hydrocarbons), which counteract the accumulation of energy of elastic deformations and the localization of gas accumulation. However, the transition from the area of liquid hydrocarbon generation to the gas window leads to a sharp increase in the volume of generated hydrocarbon gases, mainly due to the cracking of liquid hydrocarbons, that is, the emergence of geochemical triggers for the localization of coal and gas outbursts during coal mining. Scientific novelty. The new experimentally determined values of bituminous and hydrogen indices for coal seams of the Donetsk basin, and their comparison with the results within safe and dangerous mining seams, demonstrate the fact that all the studied coal samples from outburst-prone areas geometrically lie in the area of the gas window, starting from the moment of cracking of already formed liquid hydrocarbons and subsequent generation of dry hydrocarbon gases (mainly methane) due to the thermal degradation of higher carbon compounds first, and then low carbon compounds (wet hydrocarbon gases) and direct generation from the kerogen matrix. Practical significance. Established geochemical criteria that determine the conditions for the occurrence of gas-dynamic phenomena - outbursts of coal and gas during coal mining.

Methods of field geological and structural research were involved, including the kinematic method with subsequent reconstruction of paleostress fields using the program Win-Tensor. The results. On the right bank of the Danube River in the south-western outskirts of the city of Szczawnytsia (Southern Poland), numerous fold and fault deformations, their kinematic types and structural patterns were studied in the large rootless block of the PKB. Paleostress fields of the thrust, normal and strike-slip kinematic types have been restored. In the inverse stress field, thrusts were formed on the border of competent and incompetent rocks. Drug-folds, mélange and broken formations zones were formed in the more ductile rocks of the lower block. In the normal-type stress field, the former thrusts were activated as normal faults and cuted by the ortogonal and oblique sinistral strike-slip faults. The kinematic sence of the thrusts changed to an oblique normal faults with a component of the sinistral strike-slip, in the bodering zones of the activated faults, drag folds ans s-type folds were formed. In the youngest stress field, the former thrust surfaces were activated as strike-slip ones. Shear deformations were also recorded along thrust-limiting orthogonal and oblique surfaces. Kinematic types of tectonic deformation and folded structures in the different parts of the studed rootless block vitnesses the rotation of the fault wings in the horizontal and vertical planes. The wavy shape of the surface of the movement of the rootless block may be the reason for the simultaneous existence of a field of compression and tension in its various segments. Scientific novelty. As a result of the research, the kinematic types of fault, their relationships and features of development in various paleostress fields were determined. The features of the structure of the thrust and the faults that cut them, the relationships of folded and faulted deformation are established. Changes of the kinematic types of faults in time from the inverse to the strike-slip type have been established. Practical impact. The obtained results complement the history of the formation of the Pieniny Klippen Belt and can be used to refine tectonic maps and select a geodynamic model of the region.

To develop a methodology for calculating the rational parameters for walling development waies, taking into account changes in the stress state of the massif in the unloading zones of the drawn stopes of the first and second stages of mining. Methodology. To determine the patterns of stress distribution around the fringedrifts of the lying and hanging walls, located at different distances from the contact of the host rocks with the ore deposit, an integrated approach was used, including the analysis and generalization of previous studies, analytical studies of the stress-strain state of the rock mass around development waies, using the energy method and statistical data processing. Results. Studies of changes in the stability of walling development waies in the zones of influence of drawn stopes of the first and second stages of mining made it possible to establish that the stability of fringedrifts is influenced by radial stresses that arise around the drawn stopes. This necessitates taking into account the nature and degree of tension of the rock mass in the zone of unloading drawn stopes, in the process of choosing the type of support for preparatory fringedrifts, the service life of which is equal to the time of mining ore reserves in the level. At the same time, empirical formulas for calculating the magnitude of destruction of a rock mass in the roof of fringedrifts of the lying and hanging walls were obtained. On the basis of which a method for calculating the parameters of the roof bolting of walling development waies has been developed. Scientific novelty. The dependences of the magnitude of the destruction of the rock mass in the roof of the fringedrifts of the hanging and lying walls, depending on the distance to the contour of the ore deposit, the depth of the fringedrifts, and the uniaxial compression strength of the rocks, have been established.

The purpose of the work is to establish the most effective method of creating an objective typification of sections of coal seam с10в of the “Dniprovska” mine of different thickness according to germanium concentrations, based on the analysis of the clustering results. Methodology. Typification procedure is the systematization of objects according to a priori given features. Cluster analysis, taxonomy, pattern recognition, and factor analysis are usually used for this purpose. To achieve the goal set in the work, in the process of research, clustering was carried out using various methods, which are implemented in the most popular professional statistical software platforms “STATISTICA” and “SPSS”; their analysis was performed and the choice of the most optimal of them was substantiated. Excel 2016, STATISTICA 13.3 and IBM SPSS Statistics 22 versions were used in the work. Results. The main results of the research consist in the selection of the optimal method of clustering of areas of different thickness of the coal seam. The analysis of the dendrogram of the results of clustering by the weighted centroid median method of the с10в seam sections by germanium content, unlike others, allows not only to achieve the most stable division of the entire set of sections under consideration, but also to maximize the visualization of their breakdown by classes at different scale levels in the absence of a priori hypotheses regarding the number clusters and their forms. At the same time, the structure of clusters is clearly distinguished, regardless of the scale level of their formation, and the sequence of combining individual deposits and their groups into the resulting cluster is clearly traced. These advantages make it possible to make maximum use of already existing information for the development of natural typifications of areas of the с10в coal seam by germanium content and to interpret the obtained results in geological terms.

The purpose of the work is to establish and analyze the relationship between germanium concentrations, toxic elements and the content of total sulfur in the coal seam c5в of the «Ternivska» mine field of the Pavlohrad-Petropavlivka area of Donbas. Methodology. The factual basis of the work was the results of germanium, beryllium, fluorine, mercury, arsenic and total sulfur analyzes in the coal seam c5в. The content of Ge, Be, and F was determined by quantitative emission spectral analysis, Hg and As by atomic absorption analysis. Using the STATISTICA 13.3 and IBM SPSS Statistics 22 programs, the values of the main descriptive statistical indicators were calculated. Correlation and regression analysis was carried out using the methods implemented in Micromine program and their analysis was carried out in geological concepts. Results. It is substantiated that the minimum contents of at least As, Hg, Ge and total sulfur in the coal seam c5в of the \"Ternivska\" mine were jointly accumulated at the syngenetic stage of its formation. The simultaneous increase in the content of Ge and Be in the area of their low and abnormally low concentrations is caused by the joint accumulation of these elements at the syngenetic stage of coal seam formation and their increase in the area of maximum contents is caused by the manifestation of the empirical regularity of the «Zilbermints law». It is proved that the distribution of the values of Ge content, toxic elements and total sulfur in the coal seam c5в of the «Ternivska» mine differ from the Gaussian-Laplace and lognormal distributions, in all cases the polymodality of the distribution is fixed and the kernel of the distribution density is shifted to the left. Scientific novelty of the results of the conducted research consists in establishing the non-compliance of the samples of all considered elements with the normal or lognormal distribution law, while in all cases the polymodality of the distribution of indicators is recorded, which is confirmed by analytical calculations of the correspondence of the empirical distributions of the studied parameters of the Gaussian distribution using the Kolmogorov-Smirnov, Shapiro-Uilk criteria, Lilliefors and Pearson's chi-squared agreement. It is proved that the forms of finding of the investigated elements in coal with their concentrations around Clark and in coal with increased contents differ significantly. The influence of syngenetic and epigenetic processes on the nature of the relationship between Ge concentrations, toxic elements and the content of total sulfur in the coal seam c5в of the «Ternivska» mine was revealed.
