Characterization of Subsidence Over Longwall Mining Panels - Eastern Coal Province.
For Reference Only At Bureau Libraries :120 pages
The objective of this study was to describe the physical response of overlying strata to longwall mining of panels and observe changes in surface and ground water flows caused by subsidence from underground mining. The study was performed at Quarto Mining Company's No. 4 mine in the eastern coal province. The work included monitoring both surface and underground instrumentation and characterizes surface subsidence and strain, determines the potential effects of subsidence on cultural features including structures and water supplies, and develops criteria to assist in predicting subsidence for mines with similar mining and geologic conditions.
