Impact of the Hydrogeological Conditions on the Calculated Surface Uplift above Abandoned and Flooded Coal Mines

Upward surface movement or uplift has been extensively observed above abandoned and flooded deep coal mines, which used the longwall mining method, i.e., a caving method. Detailed analysis of satellite measurements indicated that process is one more complex phenomena in ground control. The linked to flooding underground infrastructure rock mass. This was confirmed by conducting analytical calculations. distribution water pressure at end phase their increase during an important aspect all estimations. main objectives study are compare impact various hydrogeological conditions this start select most realistic one.
