Keystone Bituminous Coal Ass'n v. DeBenedictis, 480 U.S. 470 (1987), is a United States Supreme Court case interpreting the Fifth Amendment's Takings Clause.In this case, the court upheld a Pennsylvania statute which limited coal mining causing damage to buildings, dwellings, and cemeteries through subsidence.
Mine subsidence has caused billions of dollars in damage in areas of the U.S. where mining once took place. In Pennsylvania alone, coal was mined in nearly half of the state’s 67 counties and there are at least 5,000 abandoned underground mines, leaving behind hazards that officials say can arise at any time.
The Knox Mine disaster was a mining accident on January 22, 1959, at the River Slope Mine, an anthracite coal mine, in Jenkins Township, Pennsylvania. The Susquehanna River broke through the ceiling and flooded the mine. Twelve miners were killed. The accident marked nearly the end of deep mining in the northern anthracite field of Pennsylvania.
Mine subsidence has caused billions of dollars in damage in areas of the U.S. where mining once took place. In Pennsylvania, where mining dates to the late 1700s, coal was mined in nearly half of the state’s 67 counties and there are at least 5,000 abandoned underground mines, leaving behind hazards that officials say can arise at any time.
Bradenville's subsidence problems are believed to be related to the Derry No. 1 Deep Mine [10] owned by Marcus W. Saxman's [11] Latrobe-Connellsville Coal & Coke Company, which mined the area beneath the town. In 2020, the Pennsylvania Department of Environmental Protection began a $5.8 million project to stabilize about 150 homes in the town ...
Pennsylvania State Police Trooper Steve Limani said early Wednesday that the abandoned mine in Unity Township where rescue crews are working to locate 64-year-old Elizabeth Pollard is becoming ...
Sinkholes occur in the area because of subsidence from coal mining activity. Rescuers had been using water to break down and remove clay and dirt from the mine, which has been closed since the 1950s, but that increased the risk “for potential other mine subsidence to take place," Pennsylvania State Police spokesperson Trooper Steve Limani said.
Mine subsidence is a risk in areas where old mining sites exist. It is a type of surface-level ground movement that happens when there is an underground collapse or shift.
