PECULIARITIES OF CONSTRUCTION OF GEODESIC NETWORK FOR DEVELOPMENT OF OPEN MINERAL DEPOSITS

Abstract

The creation of geodetic networks for open deposits has its own characteristics, in contrast to the creation of conventional geodetic networks. Surveying networks of support points for groups of quarries and individual quarries located in developed mining regions, as well as in large industrial, hydraulic and agricultural structures adjacent to cities, are being developed on the basis of existing networks of higher-class triangulation points. In the absence of higher-class triangulation points, open source support networks are created independently. The study of geodetic monitoring in mining, especially in deposits that are developed in an open way. The design of geodetic reference networks depends entirely on the shape of the quarry and the system of its opening. According to its form, choose the method of creating a planned geodetic basis. For the most part, a backbone network is created to further condense and create a film network.After analyzing the methods of creating a spatial reference network for open deposits, we concluded that the classical methods of creating a planned-height geodetic network on the territory of the mining enterprise are time-consuming, long-term and economically unprofitable. The GNSS method is the best for creating such networks at present. Of course, it cannot fully replace all methods due to various constraints, such as interference, lack of communication, and adverse weather conditions. Therefore, given the advantages and disadvantages of the methods analyzed in the article to create spatial networks in open fields, the authors consider it appropriate to combine the GNSS method with polygonometry, as the use of only satellite measurement method is impractical, but in combination with polygonometry -altitude networks for geodetic works. This combination significantly reduces measurement time, is less time-consuming, cost-effective and meets the accuracy requirements of the relevant networks. Approbation of the combination of methods for the creation of a spatial geodetic network for monitoring the open field was carried out at the Vilnohirsk mining and metallurgical plant.
