Backfilling of Highwalls for Improved Coal Recovery
There are thousands of linear miles of abandoned highwall in the Appalachian coalfields left from contour strip mining, about 25% of which are estimated to have been auger mined to depths of 100 -150 feet. Auger mining weakens the face of the highwall and makes the coal beyond the depth of augering difficult to recover (Figure 1a).
