厚3～4.8m的薄矿体占米尔加里姆赛矿床总矿量的75％。矿体厚度的减小引起深孔崩矿指标的降低。米尔加里姆赛矿床厚度从8～10m减小到3～4.8m就导致每米深孔(直径为53～55mm)平均崩矿量由4.0～4.5t降低到2.8～3.2t,从而使炸药单耗量由
Thin ore thickness of 3 ~ 4.8m account for 75% of the total ore mills in the Mill Galimu deposit. The decrease of ore body thickness leads to the reduction of deep-hole collapse indicators. The reduction of the thickness of the Millgalim deposit from 8 to 10 m to 3 to 4.8 m resulted in an average collapse amount of 2.8 to 3.2 t per meter of deep holes (53 to 55 mm in diameter) from 4.0 to 4.5 t, Consumption from
