Discussion on Hydrogeological Factors of Waste Backfilling in Abandoned Coal Mines
Waste backfilling is a widely used method in oil industry to deal with pollution or dusts and redevelop underground spaces.It provides a new way for abandoned coal mines to treat waste rocks, remediate environment and lower costs.Referred to mechanic theory and previous experiences, hydrogeological factors and their criteria for site selection were listed.Then, an analysis about related features has been carried out in abandoned coal mines.For discussing application possibility of backfilling, site selection criteria were compared with related features in closed mines.And the results showed that it seems feasibly to apply waste backfilling in abandoned coal mines for waste treatment and land remediation.Environmental risks and society influences caused by backfilling projects were the last factors for application analysis.Using backfilling for waste treatments and environmental protection will offer a high level of advanced technique, and it is also beneficial for society.
