Evaluation of the risks of the terrain surface influencing from the point of view of geomechanical changes of the rock massif due to the flooding of the mining environment of the Ostrava and Petřvald sub-basins of the OKR by mine water - final report
 Kajzar, Vlastimil
Attenuation of the remaining, still active mines of OKD company will mean the end of the primary reason for pumping mine water from mines, which is to ensure the safety of work and operation underground. At the same time, this eliminates the need to maintain the currently determined level of mine water in the already attenuated part of the Ostrava-Karviná district (OKR), i.e. in the Ostrava (ODP) and Petřvald (PDP) parts of the OKR, which are now ensured by the Jeremenko (ODP) and Žofie (PDP) water shafts. After the end of all activities in the OKR underground, the process of flooding of the abandoned mine could be started. The aim of this work is to determine the possible risks caused by geomechanical and rheological changes in the rock massif disturbed by mining activity and, above all, the associated possible risks of affecting the earth's surface.
