加拿大基德克里克矿是一个大型的现代化矿山,开采铜铅锌矿石。矿体长约500m,宽30～170m,倾角约80°,矿石围岩均属稳固,开采条件相当有利。该矿于1964年开始基建,1966年露天矿投产,月产原矿8200t,于1977年结束,开采到地表下219m的深处。露天矿下面的1号地下矿于1969年开始基建,用混合井、斜坡道开拓。深930m的混合井于1973年完工。1977年达到年产330万t的规模。采矿方
The Kidd Creek Mine in Canada is a large, modern mine that produces copper, lead and zinc ores. The orebody is about 500m long and 30 ~ 170m wide with a dip angle of about 80 °. The ore rock is stable and the mining conditions are quite favorable. The mine started construction in 1964 and the open-pit mine was put into operation in 1966. The mine produced 8,200 tons of ore per month, ending in 1977 and mining to a depth of 219m below the surface. The underground mine No. 1 below the open pit began construction in 1969 with a mixture of wells and ramps. The deep 930m hybrid well was completed in 1973. In 1977 reached an annual output of 3.3 million t scale. Mining side
