Identification of Factors Controlling the Development of Subsidence Impacts Forecasting Methodology of the I-70 Alignment over Longwall Mining of the Tunnel Ridge Mine, Washington County, Pennsylvania.
Project Report.
UNSPECIFIED, Commonwealth of Pennsylvania.
Abstract
In the winter of 2019, the Tunnel Ridge Mine extracted a long wall panel under I-70 in Washington County, PA. Additional longwall panels under other portions of the highway are planned in the future. The extraction of these panels can produce a subsidence basin with a maximum surface drops from 4 to more than 5-ft, the majority of which occurs within one or two months of undermining the roadway. This project investigates the influence of deforms during undermining with a focus on determining its transient characteristics, utilizes models to better understand subsidence impacts to the highway alignment, and where possible, determines how other future highway alignments could be impacted.
