Subject: voids caused by mined-out workings and localized depressions mining. The main consequence of Mine 1 flooding has been an accelerated and increased subsidence (vertical movement of the ground to a lower level) of the over ground land, which consists of general subsidence due to the existence of voids caused by mined-out workings and localized depressions above the points of ground-water inflow as well as possible additional localized depressions in case new points of ground-water inflow appear.Прошу помочь!
