Application of Mechanized Panel Downward Slicing Drift Cut-and-fill Stoping in Mazhuang Iron Ore
MA Yuanlei
Abstract：Combined with the characteristics of the iron ore deposit, this article introduced the application of under the tiered approach cemented fill mining method in mazhuang iron ore. The arrangement of mining layout, mining technology, filling and other processes were described in detail. The mining method under the protection of cemented backfill excavation of large cross section Approach for Mining, mining way from top to bottom, mining projects using jumbo, scraper, charging service vehicles, trucks and other large equipment transport powder. The mining safety factor is higher, panel production capacity is 15 000 t per month, the ore grade Fe is 44.96%, loss rate is 5%, dilution rate is 8%, more than one thousand tons of Mining is 6.46 m.
