3D CADASTRE. WHAT? WHY? HOW?

(SGEM Scientific GeoConference, 2006, V. Gjorgjiev, G. Gjorgjiev)

Show more

The need of real publication and distribution of the data from the cadastral systems more emphasized dictate adequate engagement of methodology and algorithms for registration of constrictive components which helps discretization of space phenomena and events. Within the turbulent ideas the cadastral systems which are functionally based on 2D treatment of property units do not have ability to accept and fulfill complex constructive segments and their contacts whit the close surroundings. This is only a part of the...

A DAMAGE IN A BUILDING EXCAVATION. REASONS AND LESSONS

(SGEM Scientific GeoConference, 2006, I. Ivanov, N. Popov, E. Beikova)

Show more

Authors consider a damage in a building excavation, which took place in June 2005 at the environs of Sofia. The slope of the excavation is protected by anchors and protective net but after the heavy rains during the whole month of June 2005 it begins to degrade. An emergency additional strengthening is made and the degradation is stopped. The paper considers the reasons for the damage and outlines the results of the investigations and laboratory tests made afterwards. The specific characteristics of the soil that ...

APPLICATION OF GPS RTK METHOD IN CONSTRUCTION OF SETTLEMENTS

(SGEM Scientific GeoConference, 2006, R. Paar, G. Novakovic, Z. Kapovic)

Show more

Global Navigation Satellite Systems (GNSS) (predominantly GPS carrier phase-based positioning) are used today more and more in various areas of geodesy and surveying. In order to determine the position of a large number of points as quickly as possible, GPS RTK (Real Time Kinematic) surveying method is the most productive one because the coordinates are obtained in real time directly in the field and involve occupying points for a short period of time. Because point positions with high precision are immediately kn...

APPLICATION OF GPS TECHNOLOGIES IN GEODETIC PROCESSES

(SGEM Scientific GeoConference, 2006, J. Eftimov)

Show more

It was successfully completed the first stage of the development of a multi-functional network of permanent GPS base stations in Bulgaria. The network receives and monitors the satellite signals from both the American network GPS and the Russian network GLONASS. The developed network allows the user to operate in real time as well as in post processing mode contributing significantly for the improvement of the measurement accuracy of the used GPS/GLONASS receiver. The system enjoys a widely spread application in f...

COMBINATION OF GPS AND SATELLITE ALTIMETRY DATA FOR GLOBAL IONOSPHERE MAPS

(SGEM Scientific GeoConference, 2006, S. Todorova, T. Hobiger, H. Schuh)

Show more

In the upper part of the EarthВґs atmosphere, the ionosphere, the free-electron and ion density is high enough to influence the propagation of electromagnetic waves. The ionosphere is a dispersive medium for the observables of all space geodetic techniques operating in the microwave band and disturbs both, their group and phase velocity. The effect is in first approximation proportional to the so-called Slant Total Electron Content (STEC) along the ray path and can be corrected if the measurements are carried out ...

DETERMINATION OF THE SAFE SLOPE ANGLES IN CHADORMALU IRON MINE OF IRAN USING EXPERIMENTAL, ANALYTICAL AND NUMERICAL METHODS

(SGEM Scientific GeoConference, 2006, A. Jafari, J. Gholamnejad)

Show more

Chadormalu Mining and Industrial Company (CMMIC) is mining Chadormalu Iron Ore deposit in Yazd province, central Iran by using conventional open pit mining method. The final pit will be excavated to a depth of approximately 225m with a bottom elevation of 1300m above mean sea level. According to the initial design, the inter-ramp slope angle of 55В° with a 30m bench height, a catch bench width of 10m and 70В° slope angle of individual benches were proposed. Mining to date has intersected complex geology and areas ...

GEOMETRIC AND KINEMATIC EVOLUTION OF PROGRESSIVE DEFORMATION IN SHEAR ZONES, SAGHEZ GOLD MINE, NW IRAN

(SGEM Scientific GeoConference, 2006, H. Hassani, M. Ghazanfari)

Show more

The Saghez shear zone is part of metamorphic belt of the Sanandaj-Sirjan zone in northwest Iran that uplifted during continental collision between the Afro-Arabian continent and the Iranian microcontinent. The mine is being exploited by open-pits mining, with present reserves estimated at 3.2gr/t gold. The currently favored genetic model is an example of porphyry system, with mineralization being closely to shear bands and emplacement of granit and pegmatitic veins. Rocks from Sagez shear zone consist of metavolca...

GPS NETWORKS AND GPS MEASUREMENTS IN THE REPUBLIC OF MACEDONIA

(SGEM Scientific GeoConference, 2006, R. Ribarovski, Z. Srbinoski, J. Jovanov, M. Nasevski, ZL. Bogdanovski)

Show more

GPS technology in geodesy is using for positioning of the geodetic points and the points from geodetic surveying in global coordinate system WGS84. In the Republic of Macedonia, as in the other countries of the south eastern Europe, were established GPS networks of the first range, but without increasing its density. If we have a fact that there are not astronomic-geodetic and gravimetrical measurements with the aim to define the local geoids more accuracy, it is clearly that can not be done massif and precise GPS...

PECULIARITIES OF FILTRATION IN HETEROGENEOUS ENVIRONMENT TAKING INTO ACCOUNT DIFFERENTIATION OF PRESSURE DISTRIBUTION IN PORES AND FRACTURES

(SGEM Scientific GeoConference, 2006, A. V. Antsiferov, E. D. Khodyrev)

Show more

The peculiarity of mass transfer in such environment is that motion between the outer surface of the blocks and their inside develops in time creating delay in the response of the blocks to pressure changes in fractures surrounding them. Analysis of these processes on mathematical models has determined that at a certain combination of the flow kinetic parameters a differentiation of pressure distribution in blocks and large fractures occurred. As a result, in filtering of poorly compressible fluids a pressure disi...

SLIP DISTRIBUTION FOR THE 1928 CHIRPAN AND PLOVDIV MAIN SHOCKS AND EARTHQUAKE TRIGGERING

(SGEM Scientific GeoConference, 2006, V. Karakostas, D. Gospodinov, B. Ranguelov)

Show more

Surface faulting and distribution of surface deformation caused by the Chirpan (M6.8) and Plovdiv (M7.0) earthquakes that occurred on 14 and 18 April 1928, respectively, were used with the scope to determine the distribution of slip and confirm the fault geometry. We assumed smooth fault geometry, based on previous studies, and a standard dislocation model. The faulting zone comprises several fault segments with different slip on each of them. For structurally complex areas like our study area the best model may b...

THE TECHNIQUE OF VERY LONG BASELINE INTERFEROMETRY (VLBI). FIRST RESULTS OF PROCESSING OF VLBI DATA IN BULGARIA

(SGEM Scientific GeoConference, 2006, I. Zdravchev, I. Ivanova)

Show more

Each of the spatial methods provides data in a different and a unique way for the three main geodetic directions: geometry of the Earth – coordinates of points and deformation; orientation and rotation of the Earth; gravity field as well as its variations. One of these methods, which is the most accurate and hopeful nowadays, is the Very Long Baseline Interferometry. In this paper it is gone into the technique of VLBI and its applications, mainly in geodesy and geodynamics. It is made an analysis of the motion o...
