Surface Subsidence Quantitative Control Method of Shallow Buried Coal Mining with Strip Mining Solid Backfilling

The inadaptability that mining under the building (construct) shallow buried coal seam with solid compacted backfilling full mining full filling pattern is analyzed based on the laws of equivalent mining height and probability integral. We analyze the necessity of strip mining solid compacted backfilling when mining shallow buried coal seam is under the building (construct) structures. On the basis of that above, strip mining solid filling design laws and subsidence quantitative control design method are proposed. At last, this method used in shallow buried coal seam mining obtained the good effect.
