• Description:
  Subsidence was monitored by the U.S. Bureau of Mines over the ends of longwall panels operating in the Pittsburgh, Kittanning, and No. 2 Gas Coalbeds of the Northern Appalachian Coal Basin. The final subsidence over the finishing ends of three panels in the Pittsburgh coalbed is compared with the subsidence measured over the rib at these panels. The characteristics of subsidence are differnt. At mine a, data over the start of a longwall panel show similar characteristics to the subsidence measured over the rib. Subsidence over the finishing ends of panels in the Kittanning and No. 2 Gas Coalbeds are also different from the subsidence over the rib. The use of a subsidence prediction model based on data gathered over the rib of a panel will not yield accurate results if it is applied to the finishing end of a longwall panel. Acceptable results may be obtained along the centerline over the starting end of a panel. [Description provided by NIOSH]
