Research on the application status and material properties of aeolian sand filling mining
摘要
Abstract
Using aeolian sand(AS)for backfilling can realize local material extraction and turn waste into treasurethe,and realize coordination of green mining and AS control.The AS filling mining is mainly applied to the backfilling of goaf under Highway,backfilling mining of coal mine and metal mine.Grouting and sand injection in the goaf,solid backfilling mining,high water backfilling mining and cemented backfilling mining are developed.Long wall backfilling mining,strip backfilling mining and roadway backfilling mining are adopted.The research on the properties of cemented AS backfilling materials focused on slurry fluidity and backfill strength.In this paper,the rheological properties of ce-mented AS slurry with different proportions and curing times are analyzed,and cemented AS backfills are toughened by using polypropylene fiber.The results showed that the rheological parameters of ce-mented AS slurry increased with the curing time,and the addition of fiber significantly improved the brittleness characteristics of cemented AS backfills.关键词
