Obnova povrchové pozorovací stanice za účelem měření pohybů povrchu vlivem dobývání v bývalém ochranném pilíři jam lokality Doubrava Dolu Karviná

Abstract

The master‘s thesis deals with rebuilding of surface observation station at former safety pillar of shafts at mining license Doubrava u Orlové of Karviná Mine. The station was surveyed in the first stage of movement observation and the positional and height connection was carried out. The second aim of the thesis is the theoretical calculation of the surface movement (subsidence and horizontal displacement) which one is caused by coal mining at the locality from 2007. The movement monitoring in former observation station was carried out at 2008-2010. The movement cause by mining in that period was calculated and compared with the measured data. The main outputs of the thesis are coordinates of points in observation station and theirs accuracy characteristics; the results of calculation of theoretical movement caused by mining at the locality and it´s comparing with corresponding measured data.
