Měření a vyhodnocení poklesů povrchu v oblasti 7. kry Dolu Karviná lokalita Lazy

Abstract

This thesis deals with stage measurement heights at the observation station by method trigonometric leveling, their points are stabilized on the surface. It´s about coal faces 140702 and 140703. These coal faces are located in excavated seam number 40. in area 7th block of the mining area Lazy (Mining plant 1). We are able to determine subsidence and shape of decrease basin from the calculated values, which are compared to the theoretical calculation of subsidence in the program. The next part is the analysis of the calculation accuracy and the determination of limits. This thesis also deals with slope evaluation between individual points of the observation station. Last but not least, this thesis also deals with the evaluating the results of horizontal movement and their accuracy.
