LOGICAL FACTORS OF FORMATION OF RADIATION BACKGROUND ON MOUNTAINOUS TERRITORY OF THE REPUBLIC OF NORTH OSSETIA–ALANIA

Posted in 2017, Issue № 3(57) March 2017, SCIENCES ABOUT THE EARTH | 0 comments

This paper considers the sources of natural radiation background in mountain regions. The presence of igneous rocks and high altitudes are the main geological factors increasing the parameter of radiation background. The results of practical research show the mountainous areas of increased radiation. The main conclusions are confirmed by measurements of the radiation produced in the areas with mining of ores and other minerals and at different altitudes as well. According to the results, the data base with geoinformation data with the radiation parameters is developed as well.

COMPORATIVE ANALYSIS OF THE CONCENTRATION AND FORMS OF EXISTENCE OF MYCROELEMENTS IN BOTTOM SEDIMENTS OF DIFFERENT AREAS OF THE VOLGA RIVER

Posted in 2017, Issue № 3(57) March 2017, SCIENCES ABOUT THE EARTH | 0 comments

The significant amount of various pollutants is accumulated in the bottom deposits (BD). Heavy metals (HM) and their compounds always pose the highest danger to the quality of water. They are accumulated in BD substances under certain conditions and may go back to water. The mass-transfer in “water – bottom deposits” system largely depends on the form of their existence in BD. Thus, the study of HM migration in “water – bottom deposits” system and receiving quantitative estimates of the mass-transfer intensity in the system during different seasons is a task of primary importance. These characteristics create the basis for definition of presence or absence of the secondary pollution danger.

DEFINTION OF OPTIMAL DURATION OF WORK FRONT AT OPEN MINING OF CARBONATE DEPOSITS OF COMPLEX STRUCTURE USING LAYER BY LAYER CUTTING MACHINES AND AUTOMOBILE TRANSPORT

Posted in 2017, Issue № 3(57) March 2017, SCIENCES ABOUT THE EARTH | 0 comments

Traditionally, drilling and fire system is used in preparing to extraction-and-loading work at development of carbonate deposits of complex structure. With all its benefits drilling and fire system has a number of shortcomings. One of its major drawbacks is the impossibility of selective mining. Layer by layer cutting machines allow to perform the thin-layer mining, improve the quality of the produced raw materials and improve the safety of the mining operations. The determination of the dependence of the work front during the development of carbonate deposits of complex structure with the usage of layer by layer cutting machines from the specific operating costs allows to reduce the production costs in practice.

PECULIARITIES OF HEAVY METALS MIGRATION AND ACCUMULATION IN THE ENVIRONMENT OF THE LAKE KULTUBAN (THE SOUTHERN URAL)

Posted in 2017, Issue № 2(56) February 2017, SCIENCES ABOUT THE EARTH | 0 comments

Coupled analysis of Cu, Zn, Fe, Ni, Pb, Mn, Co, Ba, Sc, Ti , Cd in water, bottom sediments and soils on the watershed of the Kultuban lake (Southern Urals) was performed. Main factors of metals lateral differentiation in catena were identified. Differentiation of litophile and siderophile (Fe, Ni, Mn, Co, Ba, Sc, Ti) elements are caused by natural factors related to bedrock chemical composition in autonomous and transeluvial facies. Accumulation of Cu, Zn and Cd noted in accumulative landscapes is caused by aerial input of aerosol produced by mining facilities located in the city of Sibai 6-10 km from the lake.

FORECASTING OF DEFORMATIONS OF BUILDING STRUCTURES ACCORDING TO THE RESULTS OF GEODETIC OBSERVATIONS

Posted in 2017, Issue № 2(56) February 2017, SCIENCES ABOUT THE EARTH | 0 comments

The practical results of geodetic measurements allow not only to determine deformation of structures and engineering structures, but also to predict the process of deformation. Forecasting of deformations of buildings and its parts are manufactured on the basis of information which is obtained by various methods. Processing of such data is carried out by methods of mathematical statistics with the involvement of the probability theory. This publication provides the most common used methods of forecasting of deformations of building structures according to the results of geodetic observations.

COORDINATE THE METHOD OF DETERMINING THE RADII OF CURVES ON THE ROADS

Posted in 2017, Issue № 2(56) February 2017, SCIENCES ABOUT THE EARTH | 0 comments

The article describes the method of determining the radii of curves during the construction and certification of roads with the use of global navigation satellite systems (GNSS). The formulas to determine the average square error of determining the radii of horizontal and vertical curves on the roads and the estimation accuracy. On the basis of the obtained results proved the production efficiency of the developed method. The technology of geodetic control can be carried out in modes of post processing of satellite measurements and RTK, and also allows you to determine the length of the curve
