Abstract
An abandoned mine shaft near Omar, in Logan County, WV, was permanently sealed through a cooperative agreement between the West Virginia Department of Commerce, Labor, and Environmental Research, Division of Environmental Protection, and the U.S. Bureau of Mines, Abandoned Mine Lands (AML). An engineered shaft seal design was developed and demonstrated that featured lightweight concrete as a key material component at a wet density of about 45 lb/cu ft. A reinforced concrete cap designed for 5 psi live load was placed over the shaft seal.
