CREATING MINING–TECHNOLOGICAL DATA BASE

(SGEM Scientific GeoConference, 2002, G. Siarov)

Show more

The paper treats one new for Bulgaria and for the developed countries problem – designing and creating of an Unified Mining-Technological Data Base. Passing from a chaotic mining production to one strategic directed undertaking, conformable to the environmental protection, is a process based on several main steps: 1. Defining the technological objects; 2. Defining the in-out informative data streams; 3. Defining of layers and logical connections; 4. Combining the all previous steps to one Unified mining-technolo...

(SGEM Scientific GeoConference, 2002, N. E. Ulger, G. Guzel)

Show more

GIS had been put in to application in 1987 in Istanbul Big City Municipality in Turkey. Since then, during the last 15 years, it has gained a wide application fields all over the country. In the other big city municipalities, and the other city municipalities which are belong to the big cities, and also in independent municipality organizations, GIS application has been widely started to form up fast. Additionally, in the institutions which are belong to government such as National GIS Project and National Land Re...

LASER SURVEYING SYSTEMS COMBINED WITH GIS APPLICATIONS. MODERN TOOLS IN SUPPORTING AND ENVIRONMENTAL MANAGEMENT OF MINING-QUARRYING-EXTRACTIVE WORKS. HELLENIC EXPERIENCES AND CASE HISTORIES

(SGEM Scientific GeoConference, 2002, E. Baliktsis, M. Fragoulis)

Show more

We have searched and analyzed several modern technologies aiming at the best applications of environmental management, the studying of quarrying – mining as well as the excavation sites – utilization – rehabilitation. We have used long-range reflectorless laser surveying systems, so as to achieve the fastest and most accurate surveying of the extractive work sites. We also used them, in order to collect field data, measure distances, surveying monitoring stations and environmental parameters – data. Furthe...

MAIN PRINCIPLES FOR CREATING NATIONAL GEOLOGICAL SERVER

(SGEM Scientific GeoConference, 2002, V. Trendafilov)

Show more

This paper describes the main principals and ideas for setting up the National Geological Server of the Ministry of Environment and Water (MEW), that will serve not only to present the main activities in the field of geology, prospecting, exploration and exploitation of underground resources in Bulgaria, but also to present to the public available collected geological information by the means and popularity of the Internet technologies. As National, the geological server will present Bulgaria and will be part of t...

MANAGEMENT SYSTEM FOR SPECIALIZED MINING-GEOLOGICAL INFORMATION

(SGEM Scientific GeoConference, 2002, G. Siarov)

Show more

This paper analyses the “frame” of one mining-geological informative system. Here are examined the information as a resource, data bases, middle-tier and n-tier servers of information, text and graphical streams of data - and all that combined in a modern IT-technology, which is the needed key. The key that has not opened yet, the development in the mining production in Bulgaria and perhaps in other countries. The awful, for some “specialists”, words and terms as Database, Oracle, CAD,GIS, Layers and etc. ...

MONITORING OF CHANGES IN MEASUREMENTS OF OBJECTS FROM PHOTOGRAPHS

(SGEM Scientific GeoConference, 2002, L. Lichev)

Show more

The paper acquaints us with the sphere of science photogrammetry, especially then with mining and digital photogrammetry. Using knowledge from this area of science a system FOTOM2001 was developed, which serves namely for measuring the profiles of vertical mining holes using photogrammetry, newly also for measuring the data in other areas (for example rentgenology). In the paper, the system is described along with its functions especially with respect to the newly added modules for measuring divergences of data an...

ON THE APPLICATION OF GEOPHYSICAL COMPUTER TOMOGRAPHY FOR AN INCOMPLETE SET OF DATA

(SGEM Scientific GeoConference, 2002, V. Dimova)

Show more

The basic task of computer tomography for reconstructing the body by its projections for an incomplete set of data is solved by using Radon’s retransformation and subsequent regularisation. The method proposed can be used successfully in geophysics and geotechnology.

THE REGULARIZED MOORE-PENROSE PSEUDOINVERSION METHOD AS A TOOL FOR MEASUREMENT DATA PROCESSING

(SGEM Scientific GeoConference, 2002, V. Dimova)

Show more

The Moore-Penrose pseudoinversion method applied in solving systems of linear algebraic equations with incorrectly prescribed data lead to unstable solutions. This makes the method inapplicable in practice. The regularised version of that method is described which can be used as a basis for data processing in all branches of applied earth sciences.

TOOLS OF AI FOR OBJECT RECOGNITION IN SYSTEM FOTOM 2001

(SGEM Scientific GeoConference, 2002, L. Lichev)

Show more

The recognition of points of interest leads to the detection and consequent specification of the values of Xi and Yi coordinates. The result is a data file of the coordinates. The problem domain is divided into two parts. The first one includes the processing of graphic information, while the second concentrates on searching for the points and objects of interest.

A CONTAMINATION SOURCE IN S. SLOVAKIAN KARST AND THE PROPOSAL OF A GIS BASED MONITORING SYSTEM

(SGEM Scientific GeoConference, 2001, L.Tometz, G. M. Timcak, P. Blistan)

Show more

The paper elaborates the risks of underground water contamination in the Slovakian Karst. First the geology of the area is given, then the hydrogeologic background is detailed. A number of measurements were taken in the vicinity of a crude oil pipeline that indicate the high risks of having the pipeline there. Lack of in-built monitoring system in the pipeline may increase the risk. Finally a GIS based monitoring system is proposed.

The geological information in Bulgaria is state property or co-property of the state and holder of license for prospecting and/or exploration or of the concession for exploitation of underground resources. Upon termination of the license or the concession the entire information becomes property of the state. The National Geofund of the Ministry of Environment and Water is responsible for collecting and storing all geological data in Bulgaria. Part of the data is published. The National Geofund is in charge of disc...

NEW APPROACHES TO MINING PHOTOGRAMMETRY USING PC

(SGEM Scientific GeoConference, 2001, Lacezar Licev)

Show more

This contribution engages in mining photogrammetry as a relatively new branch of photogrammetry. It describes a system, which is divided into two modules. The first one is used to describe single objects on a snap, the second one performs a synthesis of all the snaps. New expansion of this branch is made by solving photogrammetric problems on computers. The photogrammetric system FOTOM was used to solve a particular task in mining photogrammetry. The system is an integral system on a qualitatively better level the...

The Hornad river is a tributary of Tisa. It flows through Slovakia and Hungary. The environmental data on the Hornad river that were collected within the RECENT, DECENT and SOSNA projects since 1995, were embedded into a number of databases and simple GIS systems. Recently, the data were integrated into the new EnviGIS system created as a project within the ArcView environment. The EnviGIS - apart from digital maps contains databases of water and environmental quality data plus data on selected waste deposits alon...
