Timing and duration of subsidence due to longwall mining. Report of investigations/1995
Technical Report
·
OSTI ID:80568
Subsidence data gathered by the U.S. Bureau of Mines over a series of longwall panels in the Pittsburgh Coalbed were studied to obtain insight as to the role of time in the subsidence process. IT was found that subsidence began essentially with undermining and was completed within one year. The progress of the subsidence was dependent upon location above the panel. All sites behaved similarly in the central portion of the subsidence trough. However, the subsidence of points over the adjacent to the ribs of the longwall panels was site specific.
