Cemented boreholes annulus its stability achieved tightness must be maintained in the continuation phase of drilling, is that in the process of drilling, cementing, production. Preserving stability in the working life of the wells threatened and technological stage of the production process due to the natural development of conditioned stress-laden...

As it is known, the extraction of rock salt from deposit “Tetima”, Majevica, performed is by controlled leaching in the underground chambers positioned diply in the salt deposit. The connection between the underground chamber, that represents the basic production unit in the primary salt production and technological installations on the surface, is...

The landslide is located in the hinterland of water source "Studenac" in the local community Gornja Cadjavica near Bijeljina. The field where the triggered landslide occurred is conditionally stable slope. It is overgrown with forest trees and therefore it was not a subject of interest in terms of its stability until the water source and accompanyi...

The hydrogeological investigations are inevitable in the whole process in defining of engineergeological field characteristics and the drafting of landsllides rehabilitation project, but the main goal of these investigations is the groundwater quantities calculations in critical sections of landslides. For gain of exact input parameters for groundw...

Earthquakes are one of the biggest hazards of humanity. Even today it is not possible to predict the exact magnitude, location and time of an earthquake, but, nevertheless, modern seismology and science are able to point to the potential danger and risk of earthquake-like movements in an area, at one time. Some of the signs that announce the earthq...

Using of explosives in modern mining is very important for the good, efficient and rational organization for obtaining of solid minerals, especially in the exploitation of mineral resources on mines with large capacities. Technological phases of drilling and blasting in the exploitation process are very important in this case, and the analysis in t...

This paper presents one approach for the analysis of snap behaviour of simply supported elastic shallow shells. Structure is discretized with the finite strip method. Displacement field is approximated with series of products of polynomials and harmonic functions. Only geometric nonlinearity of von Karman type is considered. Equilibrium equations a...

During the past two decades, rapid advances in information technology have improved the accuracy and capabilities of optimization techniques. Unfortunately, great number of optimization methods in civil engineering has not found implementation in practice, mainly because the problems were treated only from mathematical point of view, disregarding a...

Before the electronic distance meters appears the angles measuring dominated in geodetic networks. Development of distance measuring technology and appearance of automated total stations almost equaled the efficiency of measuring angles and distances. This fact allows designer of geodetic networks to combine angles and distances in order to achieve...
