摘要

This paper introduces the classification of the coal backfill mining method and analyzes current technology statuses of several coal backfill mining technologies: waste backfill mining technology, paste backfill mining technology and abscission layer grouting backfill mining technology. Based on the analysis of current backfill mining technology statuses, this paper puts forth that the backfill mining technology should focus on the problem of the lack of coal backfill mining capacity, research on the role of backfill mining rock movement needing to be strengthened, filling efficiency and economy needed to improved through reasonable optimization of backfill mining parameter, so it can provide the theoretical basis for backfill mining design.
