Ground Control Monitoring in Backfilled Strip Mining under Surface collapse control under thick unconsolidated layers

Ground subsidence and coal gangue induced by mining activities could significantly influence the nearby environment To allow strict public scrutiny of mining under the metropolitan district coal gangue backfill has been introduced together with the strip mining method to minimize ground subsidence and to reduce gangue disposal in Tangshan Mine in Hebei Province China Field investigation A backfilling strip mining field trial was conducted in No 2 mining district of the coal mine in Shandong Province The length of the longwall face was designed to be 55 m and the width of the coal pillar between adjacent panels was 25 m The actual mining height was designed to be 50 m which was equal to the thickness of the coal seam The compression ratio of the solid backfilling
