Subsidence Monitoring in Conjunction with Underground Mine Flushing Operations
Based on subsidence monitoring, findings regarding the degree of land surface stability are reported at two sites in Scranton, Pa., which overlay multiple levels of abandoned coal mines of the Northern Anthracite Field. The project, sponsored by the Federal Bureau of Mines, Division of Environment, entailed periodic measurement of minute surface deformations--vertical and rotational--in developed areas in which the mine cavities had received roof-supportive hydraulic backfill materials, pressure-injected through boreholes.
