Interpretacja badań mikrograwimetrycznych przeprowadzonych na planowanym odcinku autostrady A-1 w rejonie Piekar Śląskich
(Data obrony: 2011-10-10) Zięba, Maciej
Wydział Geologii, Geofizyki i Ochrony Środowiska
The mining of zinc and lead ore for centuries existed in the area of Piekary Slaskie after ere was depleted, hard coal was extracted. Many of these mines, shafts, adits has never been properly liquidated. This led to situation in which many areas have been susceptible to deformations. The task of the thesis is interpretation of the micro – gravity survey conducted by the Department of Geophysics, AGH University of Science and Technology Faculty of Geology, Geophysics and Environmental Protection coordinated by Ph. D. Janusz Madej, assistant professor on planned route of the motorway section A1.

Interpretacja badań mikrograwimetrycznych przeprowadzonych w południowej części Inowrocławia
(Data obrony: 2011-10-18) Piecuch, Marcin
Wydział Geologii, Geofizyki i Ochrony Środowiska
Salt dome which is located shallowly beneath the of Inowrocław, had a strong influence on the terrain of the city. The the rock salt has been mined for many years. Unfortunately, exploitation had a strong influence on the development of karst phenomena in the cap and the dome. The task of the thesis is the interpretation of micro-gravity research results conducted in the southern part of Inowrocław to determine the location and parameters of the zones of reduced density.

Interpretacja badań mikrograwimetrycznych wykonanych wokół szybu IV KWK „Bielszowice”
(Data obrony: 2011-10-10) Misiołek, Tomasz
Wydział Geologii, Geofizyki i Ochrony Środowiska
The aim of this paper is to interpret and evaluate the data provided by the Department of Geophysics at the Faculty of Geology, Geophysics and Environmental Science of the the ‘AGH’ University of Science and Technology in Kraków. The measurements were taken at mineshaft no. 4 of the Hard Coalmine ‘Bielszowice’, using the microgravity method. All the measurements were conducted by the Department of Geophysics, under the auspices of professor Janusz Madej. My evaluation of the data is to determine whether there are any existing fissures or incongruent areas in the vicinity of mineshaft no. 4 of the Hard Coalmine ‘Bielszowice’, which could constitute any potential risks for the stability of the shaft itself or its surrounding infrastructure.

Model grawimetryczny budowy geologicznej na odcinku Chochołów–Jordanów
(Data obrony: 2012-03-02) Jamro, Paweł
Wydział Geologii, Geofizyki i Ochrony Środowiska
Geological profile section Chochołów – Jordanów runs through the main building units of the Carpathian Mountains, including the division of the Inner Carpathians and Outer Carpathians. Major elements of the construction of this profile is the Orava Basin, PKB, Magura Nappe, ground, and pieces of the Podhale Basin. The paper presents an analysis of measurement data section Chochołów – Jordanów and their processing and account amendments such gravity topographic correction, Bouguer and Faye's anomaly. Explained the concept of gravity anomaly on which to base an analysis of the data. By processing the data obtained Bouguer anomaly curve, which consists of regional and local anomalies. Modeling, which results in the section gravimetric model of Chochołów – Jordanów created using ModGraw by Dr. Eng. S. Porzucek.

Program do profilowego modelowania grawimetrycznego 2,5D
(Data obrony: 2012-09-27) Biernacki, Kacper
Wydział Geologii, Geofizyki i Ochrony Środowiska
The aim of this thesis was the creation of an application programfor2.5Dgravitymodelingacross the profile. The program allows the approximation of objects with four blocks and use them to modeling the effect of gravity, so that it is possible to adjust the measured and modeled curves. In the first part of the thesis are presented the theoretical basis for gravity modeling, the general outline of the program and a description of its functionality and technology used for application creation. In the second part has been discussed in detail the process of creating the program and individual functionality, and provides algorithms for data processing and error handling used in the program.

The relevance of the study of regularities of karst development of the Carpathian sulphur basin is conditioned by the searches of the best method of development and mastering of deposits of sulphur, further development and increase of her production in the conditions of mining-and-geological complications of booty and activation of technogenic karst, by the necessity of further development of scientific questions of karst formation. A great importance here has reliability of tracing contours of sulfur melting zones, that differ from a surrounding sulphuric layers the relative reduction of density. Identification, mapping and control of the development of such decompression zones can be done based on the results of detailed high precision gravity observations before and after the industrial sulfur melting using automated interpretation. The aim of this master’s work is a substantiation of application of the gravitational monitoring, as an effective means to control the state of the melting during the exploitation of native sulfur by underground melting method. Data of which provide the increase of efficiency of the re-melting and allow to estimate the ecological condition of cut within the limits of sulphuric layers so above them. First of all, the work was the analysis and synthesis of the totality of available geological and geophysical information obtained from the results of research of IFNTUOG and Spetsheolohorozvidka. An important part of the work is to perform a gravity simulation modeling from the expected decompression zones by a computer program „Complex.Gravity” (S. Anikeev 1994-1999). Simulation modeling is directed to the estimation of geological efficiency of the interpretation of geophysical data, specified on possibility of reliable determination of zones of the intensive melting of sulphur by means of computer interpretation of gravimetrical materials. Gravity modeling, ie the solution of direct and inverse problems of gravimetria helps to make detailed studies and contouring of decompression zone both in plan and in incision of deposits. This method of quantitative interpretation of space-time anomalies of the gravity field based on the use of computer technology to refine and detailing a density models of geological environments. Work violates the problem of resolution of the gravity field, which depends on the depth, size of sulfur melting zones and melting intensity. Through modeling which is made in MathCad environment, considering the real geometrical parameters of decompression zones and a density of rocks of the typical cut of sulphuric deposits, are defined the optimal parameters of the detection anomaly from the zones of sulphur melting. Ultimately, was confirmed efficiency of using gravimetria to monitor the karst processes on the areas of underground sulfur melting.
