Vylegzhanin O. N., Rybalka S. A. Calculation of coordinates of anunknown point based on the results of remote and directional measurements from known points – p. 20

The analysis of requirements to a standard problem of a geodesy – to definition of coordinates of an unknown point by results of directional and remote measurements to it from points with known coordinates is carried out. The basis of the proposed general approach to solving this problem is the formation of a system of linear algebraic equations. We describe the algorithms for solving the problem under discussion. The efficiency of the described algorithms confirmed by the decision of test cases.

Keywords: geodesy; mine surveying; method; measurements; accuracy; distance; vector; system of linear equations.

 

Gleyzer V. I., Vladimirova T. M.  Evaluation of measurement uncertainty mine surveying gyrocompass – p.24

The paper states the significance of the gyroscopic orientation technology for the surveying tasks of mining and metro engineering, as well as a number of other industries. It considers the issues of metrological support of the instrument base of this technology, i.e. terrestrial gyrocompasses (survey gyrocompasses, gyrotheodolites, gyro stations, etc.). As the national metrological practice is inevitably influenced by the process of international standardization of the measurement quality assessment, which is based on the concept of “measurement uncertainty”, this new approach to the problem of metrological support of gyroscopic instruments used in modern surveying practice and related industries is considered.

Keywords: gyroscopic orientation; terrestrial gyrocompass; metrological support; measurement uncertainty assessment.

 

Shmonin V. I., Shmonin A. B.  Mine surveying monitoring of deformations of the earth’s surface and engineering structures in the development of hydrocarbon fields fnd ways of its optimization –p.31

The article examines the issue of optimization of mine surveying monitoring of deformations of the earth’s surface and engineering structures in the development of oil and gas fields. To reduce expenditure on the creation of geodynamic polygon optimization are proposed in three areas: the gradual establishment of networks for geodynamic observations; differentiated approach to the choice of methods and means for measuring deformations of the earth’s surface at every stage of field development; a rational choice of time and frequency of observations. To implement the optimization process of the proposed algorithm is a sequence of actions.

Keywords: deformation; mine surveying control; monitoring; optimization; geodynamic polygon; rock mass; the earth’s surface.

 

Malyutin Yu. A. Geological and structural block model of the Elanskoy nickel deposit and calculation of recoverable reserves. Part 1 – p.37

The purpose of this paper is to compare traditional approaches to the calculation of reserves of ore deposits in our country and the international methodic in the conditions of a market economy to the estimation of ore deposits using the example of 3D-modeling and the evaluation of the Elanskoy nickel deposit.

Keywords: ore deposit; calculation of reserves; 3D-modeling; Elanskoy nickel deposit.

Terentyev V. B. Identification of trends of destruction of layers in the development of weakened parts of verkhnekamsk deposit of potassium and magnesium salts – p.44

The article presents the results of field observations at deep monitoring stations installed in areas with weakened geological structure of the Uralkali mines of the Verkhnekamsk deposit of potassiummagnesium salts. The stations are installed in the bearing layers of technological interlayers AB-KpII in order to study the pattern of their deformation in time. The graphs of the stratification are constructed, the relative deformations and strain rates are determined, and the correlation dependences are obtained.

Keywords: technological layers; the geomechanical system; underground monitoring stations; the process of displacement; velocity of seepage of bearing layers.

 

Kolesatova O. S., Romanko H. A., Kartunova S. O., Khonyakin B. N., Krasavin A. V. Substantiation of steady parameters slope of the pit kamaganskaya taking into account fracture of side rock mass – p.49

Assessment of open pit walls stability and the justification of their parameters during the development of deposits with geotechnology methods is an actual scientific and practical task. The assessment of Kamaganskaya deposit walls stability is made with the method of force polygon in three-dimensional formulation of the problem taking into account the structural-tectonic fracturing of near edge rock mass. It was established according to the results of calculations that with the actual pit outline the stability factor is too high, which will increase angle of slope of the pit up to 500.

Keywords: deformation of the open pit wall; tensor probabilistic model; sliding wedge; open pit walls stability; polygon of forces; stability factor.

 

Smirnov A. V., Dubovik A. I.  Field measurements in haulage drifts of GP «Coal company «Krasnolimanskaya» – p.55

Тhe article presents the results of the performed haulage in mines of GP «UK «Krasnolimansky» field measurements for the study of the regularities of deformation of geomechanical system «drift–lava». It is established that deformation of rocks soil begin approximately at a distance of 80–100 m from the bottom of the lava, are non–linear, and after Podravka have less intensity. The collapse of the rocks of the immediate roof occurs at a distance of 5–10 m outside the lava, but the smooth lowering of the main roof at a distance of 20–30 m.

Keywords: conveyor drift; heaving rocks of the soil; the smooth lowering of the roof rocks; thegeomechanica lsystem.
