While analyzing and managing the mining production we are leading not by the mine itself, as an object, but mainly by its model. In that case every taken decision will be workable only if we have a realistic model, completly describing every specifications and characteristic of the mine. In the article we will describe mine modeling algorithms and some requirements of mine computer modeling too.

World Summit for Sustainable Development (WSSD) in 2002 in Johannesburg formulated approaches to ensure geographi\'\ical information support of the tasks formulated in Action Plan of WSSD. Author of the paper understands sustainable development as a set of equel and necessary aspects: ecological, economical, technological, social, cultural and ethical.

The degree of toxic metals contamination in water, vegetables and respective soils in the studied area - KCM Smelter site - Plovdiv-Assenovgrad is evaluated in individual and integral aspects. The analytical measurements were performed by inductively coupled plasma atomic emission spectrometer (ICP-AES), Jobin Yvon ULTIMA 2. The analysis lines in the determination of impurities were selected in view of spectral interference. Ground, surface, waste - water and some corresponding soil samples were investigated for m...

The Internet management is not an open process, as well as there is a lack of an information flow, where one could benefit from the information using speed,but not from hiding and misusing the latter. To appear through Internet in front of the professor for a diploma or face to face as a half-wit after electroning training. An ecologyc way of life as a balance between the two opportunities. Is the Internet a public space?Who is Internet?

Development of information technologies for the recent years converted the information into a powerful resource, providing more and more various spheres of production. And the new methods of acquiring, managing and saving different types of information created the information systems. Geoinformation systems (GIS) unite a vigorous mechanism for layered information acquiring, separated to two major information flows, respectively - spatial and descriptive, with absolutely automated functional relations. GIS has a co...

This work shows presents an overview of the basic morphological techniques and some of their applications to important tasks in geosciences including radar image segmentation and despeckling, object detection on aerial photographs, analysis of images of bore holes etc.
