Decision making can be defined as a selection process of the best one among the alternatives sets in order to obtain goal, and mostly has an uncertain situation. Additionally, mostly linguistic variables (weak rock, massive ore deposit, etc.) become in question. Mine planning engineers often use of their intuition and experiences in decision making. As the fuzzy set theory was carried out since 1970, these uncertainties in question are easily evaluated in decision making process. Real world study is decision makin...

As the complex ore quality of "Tenka" ore body in Majdanpek is similar to all mineralisations that are morphologically presented as irregular lenses and veins, it is necessary to introduce the technological process optimization applying the automatic control. The optimization conditions of the main operation parameters in grinding, flotating and dewatering are found in the research work in order to obtain the bulk concentrate with more than 53\% (Zn + Pb) and Cu less than 3.0\%. In the grinding process, some optim...

The article aims to clarify the ways of acting of the contemporary methods for land volume calculation in open pit mines. Here are discussed the fundamental ways for receiving and analyzing of field captured data through specialized software products.

The "Propast - Dobrovolec" Mine produces bentonite clay by open pit mine technology. This report presents mining and geology characteristic of the field. Here are given the results from the determination of the physical and mechanical indexes of clay and rocks. The slope angles of the benches are determined by the combined schemes of V. Felenius, and for the general pit edged angles are used Prof.Fisenko’s methods (VNIMI - Sankt Peterburg).

There is no doubt that the energy potential of a country is directly influencing its economic and technological development. The potential of the Republic of Macedonia is based on the Pelagonian and the Kichevo coal basin. However, water resources, participating with 29 percent, have also a significant influence upon the energy balance of the country expending with the construction of new resources. This is even more so, considering that, by the construction of new resources, they have been permanently upgrading, ...

As a result of executed examinations a phenomenon of formation of moving broken zones in the tight rocks encompassing by volume experimentally is established that at transiting in rocks of a wave of change of a tension of a mining massif (for example, a wave of the Weber), at the front of longwall there is a fracture of soils stipulated by an operation of tensile stresses.

The problem of surface site protection in mining areas consists in finding such an order of mining that an exactly determined subsidence is obtained on the ground surface. The aim is achieved by solving Fredholm’s integral equation of the first kind. This problem is ill-posed. It is solved by using Tikhonov’s regularisation method.

Paper deals with methods applied in process of measurement of objects on a photography. Basic principles of 2D and 3D modeling of measurement process are described. Next, solution of computer animation is discussed.

Construction of a mine (in this case of an open pit) is a demanding and multidisciplinary project following the sequence of preparatory activities. The incompletely/inadequately conceived activities can lead either to a prolonged preparation of mine construction or to the misdirected investment. Introduction of computer technology in this process enables shortening of time limits but emphasizes the importance of preparatory activities and exploration works. During the phase of preparatory activities, changes in th...

Recognition of points of concern leads to detection and consequent specification of values of coordinates Xi and Yi. Result is data file of the coordinates. Problem domain is divided into two parts. The first one discusses processing of graphic information, while the second concentrates on searching of the point of concerns.

The paper deals with photogrammetric diagnosis of underlay and rigging deformations of air- and preliminary- shafts equipped with exploit devices. Collieries are basic connective, transport and airy link between underground working and over-ground devices. Technical conditions of these collieries influence directly their trouble-free working, staff safety and certainty of underground working. Documentation of factual states of up-and-down collieries is topic of the paper. The paper presents development of software...

The enclosed abstract describes survey-technological management as a vital base and precondition for the successful development of mine producing. Here is presented a comparative analyze of working process with all these new computerized technologies, which strengthen their position from day to day, by those mine enterprises, who are opened for the innovations of our century. Human resource, technologies and requirements are those factors that defined this new way of thinking and working. Nowadays, technological s...
