بيت /define subsurface mining vs surface
Subsidence is a timedependent process, either natural or man induced, in which there is a lower ing of the ground surface in response to the re moval of gas, liquid, or solid matter. Deformation of the rock mass may be by either elastic, plastic, or brittle processes or by any combination of these processes.
