Geodetic Support for the Identification of Polynomial Break Points on the Mining Subsidence for GIS Applications

Currently, in the highly developed industrial world, safety and protection of human lives and their property against the negative impacts of the industry should be a priority task of each its sector, not excluding mining. The impact of mining activity on the environment is very negative industrial influence. As a result of underground mining activities in the surface creates mining subsidence. Conditioning factors to establish the extent of the movement of the surface above the mined out area are a geodetic way surveyed deformation vectors which can be derived from the processing of measurements at monitoring stations. The theory for the estimation of polynomial break points in the case of the subsidence analysis is presented. The theory was developed as a part of the kinematics analysis procedures for the evaluation of the magnesite deposit in the suburb of Kosice-Bankov on the northern outskirts of the city of Kogice （eastern SIovakia）. The subsurface abandoned mine Kosice-Bankov is located in the immediate vicinity of the recreational and tourist zone in the northern suburb of the city of Kosice. The numerical and graphical results from the break points estimation in the magnesite deposit Kosice-Bankov are presented. The obtained results from the abandoned mining area Kosice-Bankov were transferred into GIS for the needs of the municipality of the city of Kosice in order to conduct the reclamation of this mining devastated landscape.
