|Partial backfilling can be used to reduce and control surface subsidence damage caused by longwall mining or pillaring operations in room-and-pillar mines. The use of partial backfill as opposed to total backfill minimizes the cost associated with such efforts. By com- paring surface subsidence, strains, and slopes, the effectiveness of partial backfilling including the amount, geometry, and location of backfill are demonstrated. Results show that it is possible to arrange a given volume of backfill in its geometry and location so that optimum effects are achieved in controlling vertical movement, surface slope, and curvature.|
