兰尖铁矿是大型山坡露天矿,矿石为钒钛磁铁矿,围岩与夹石主要为辉长岩和大理岩,矿岩硬度较大,但由于节理发育,除中、粗粒辉长岩、大理岩和一级品矿石之外,可爆性较好。矿岩的普氏硬度系数见表1。兰尖铁矿采用4~4.6立米电铲,采场用T-20和北京371型汽车运输。矿石通过平硐溜井用百吨翻斗车和150吨电机车运往选矿
Lanjian Iron Mine is a large open pit open pit. The ore is vanadium titanomagnetite. The surrounding rock and clayey rock are mainly gabbro and marble, while the mineral rock is relatively hard. Due to the joint development, the medium and coarse grit Rock, marble and a grade ore, the burst is better. The Plankton hardness of rock is shown in Table 1. Lanjian iron ore using 4 ~ 4.6 m shovel shovel, stope with T-20 and Beijing 371-type car transport. Ore through the adit with a hundred tons of dump trucks and 150 tons of electric vehicles transported to dressing
