MAPPING OF NATURE RISKS AND DISASTERS FOR EDUCATIONAL PURPOSES

(SGEM Scientific GeoConference, 2006, T. Bandrova, M. Konecny)

Show more

The paper presents definitions of nature risks and disasters. The mapping of the risk processes is discussed in the direction of educational purposes. International organizations publish information brochures about how to teach children correct behavior and preparation for natural disasters. Questions as “What do you do in case of an emergency” are discussed. Standards and technologies related to emergency management are considered. Some examples of maps and methods of mapping for young and older students are ...

MINE WORKING STABILITY CRITERION

(SGEM Scientific GeoConference, 2006, V. Dryban)

Show more

Based on a two-level model for the zone of non-reversible deformations that is produced near mine working, bifurcation-type criterion is developed for stability of heterogeneous rock mass. A new approach to calculate parameters of mine working lining has been proposed. It is based on the treatment on energy balance of “lining-rock mass". Geomechanical criteria of mine working lining stability are obtained.

RELATIONSHIP BETWEEN INTERACTIVE EDUCATION IN DIGITAL PHOTOGRAMMETRY AND IMAGE PROCESSING

(SGEM Scientific GeoConference, 2006, D. Marinov, P. Draganova)

Show more

The main principles and methods of interactive education are discussed. The requirements to this approach of educational process are formulated. The differences between practical training and learning process are discussed. Based on these principles there are shown the examples for deductive education on processing stages in digital image processing and digital photogrammetry. Main attention is pointed to the initial data collection for purposes of inner orientation, image calibration and relative orientation of s...

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...
