Biography

Actuality of theme

Planning of conducting mountain works and mineral working off is impossible without construction in underground mountain developments of a uniform network of the strong points which spatial co-ordinates should be defined with necessary accuracy in uniform nation-wide system of co-ordinates.
The given theme «the Establishment of dependences of accuracy of creation underground surveyor supporting network from the basic influencing factors» is actual, since. Now pressing question is the estimation of reliability underground surveyor supporting network created in deformable mountain developments.
On accuracy of creation underground surveyor supporting network a great influence errors of angular measurements render, errors of linear measurements, to an error of measurements of co-ordinates of starting points and direktsionnyj corners of the initial parties, an error girrostoron. These errors also make essential impact on an error of position of the most remote point underground surveyor supporting network. All it is necessary for an estimation of accuracy existing and projected underground surveyor supporting network.

Purpose and research tasks

The purpose of this work consists in establishment of dependences of exactness of creation of underground surveyor supporting network from basic influences.
For achievement of the put purpose the followings basic tasks are formulated:
- it is an analysis of influencing of error of measurings in the networks of subterranean poligonometric passage;
- development of algorithm and programmatic facilities for the analysis of exactness of underground surveyor supporting network;
- it is an analysis and interpretation of error of points of underground surveyor supporting network.

Idea of work and object of researches

The idea of work consists in the use of conformities to law of accumulation of errors of measurings depending on configuration of underground surveyor supporting network.
The object of researches is an underground surveyor supporting network.

Scientific novelty and practical value of the got results

A scientific novelty consists of that an algorithm and programmatic facilities is developed for the analysis of exactness of underground surveyor supporting network.
The practical value of the got results consists in introduction of the developed methods of estimate of errors of points of underground surveyor supporting network on a production.

Basic maintenance of work

During exploitation of deposits of minerals there is a row of mining-geological tasks, for the decision of which not walked around graphic system of the mountain making image. It is arrived at by means of gasket on the mountain making of mines of poligonometric and level motions with the subsequent calculation of co-ordinates of surveyor points, heights and construction of plans of the mountain making. Considerable increase of sizes of the mine fields and depth of development, wide introduction of the mechanized complexes and conveyer transport of minerals, and also process of enlargement of mountain enterprises, were those factors which stipulated a necessity for the construction of the exact and reliable underground planned ground [2].
For the decision of of mining-geological tasks, such as a surveyor providing of sboek, construction of underground surveyor supporting networks, it is required to describe the surveyor points used as the planned basis from point of exactness. As such description the middle is used quadratic errors positions of points of surveyor ground.
For more exact determination of co-ordinates of surveyor points the special methods of creation of ground are used (gyroscopic orientation of additional sides, use of more exact devices)[3].
Thus, the estimation of exactness of planned s'mok must be made a surveyor, which the middle quadratic errors of position of points must be certain during. These errors must be taken into account at the use of points as the planned ground for the production of surveyor s'mok and decisions of other of mining-geological tasks [4].

Conclusion

In this work the program of calculation error of point is developed created and design underground marsheyderskoy to the supporting network. Taking into account bulkyness and complication of algorithm of calculation of middle quadratic error of points of underground surveyor supporting network, it is necessary to notice, that the decision of this task is possible only on the basis of the use of computer technology.
Application of the offered computer estimation of exactness of underground surveyor supporting network will allow to carry out the search of optimum this network configuration, localize the places of location of groups of permanent points (girrostoron), choose the optimum method of implementation of the field measurings.
Further development of the offered technology consists in providing of possibilities of operative prognosis of exactness of determination of co-ordinates of points, created and reconstructed underground surveyor supporting network.
