摘要

After a long period of mining, the Lishugou coal mine is left with large mined-out areas and numbers of waste heaps, causing ground collapse, land subsidence, geofractures and other geological disasters. The cultivated land, vegetation, water and air environment have been severely damaged. To locate the mined-out areas, the geophysical exploration and drilling techniques are adopted. The damage degree of bridges and roads are investigated on the spots. The technical methods of drilling and backfilling, perfusion, moving and leveling are used. Different construction plans and technical requirements are made for the recovery of geological environment of the coal field.
