Figure 2. A representation of a "mine spoil pad" constructed to support an intended building site during reclamation. The spoil pad should extend beyond the minimum area required to support the actual building. In most cases, the zone where the surface is compacted should extend at least 10 feet beyond the intended footing area. The compacted spoil pad should extend downward at a minimum angle of about 30 degrees from the vertical (a 2v:1h slope).
