Overburden Strata Movement And The Impacts Of Longwall Mining On Groundwater Systems In Shallow Seam-a Case Of Cumberland Mine Panels B5and B6

In this research, the post-subsidence strata movement and overburden groundwater have been modeled using the FLAC3D and GGU-SS-FLOW3D program, respectively. These models tries to describe the every single layer movement and produce physical hydraulic environments to evaluate the effects of longwall mining on strata movement and groundwater flow system. This study is a site-specific hydrogeologic analysis conducted before, during and after longwall mining at a site located over the selected longwall panels B5and B6. Data from subsidence, surface water table observations and extensometer readings over the study panels were collected, complied and analyzed. The purpose of this study is to provide documentations of the strata mechanics and ground water fluctuations caused by longwall mining.
