随着生产的发展和条件的改变,我矿各坑口的生产工艺也在不断改进。例如,对原来用电耙绞车耙矿或气闸门放矿的坑外贮矿仓,从1986年起先后改用自制的仿ZF—2型振动放矿机放矿,日出矿量800～1100t,完全满足了生产需要。 1.夹皮沟矿概况该矿位于浑发河大断裂带。矿石硬度f=8～12;自然安息角θ=38～40°;比重2.8t/m~3;松散系数1.6。该矿采用井下深部开采,有四大生产坑口,立井深达56m,双井筒双罐双层罐笼提升,属中型矿山,已开采160多年。
With the development of production and the change of conditions, the production technology of each mine pit in mine is also constantly improving. For example, the original electric rake winch rake mine or gas release mine pit outside the ore storage warehouse, since 1986 has switched to homemade imitation ZF-2 vibration ore miner ore release, sunrise mine 800 ~ 1100t , Fully meet the production needs. 1. Overview of Jiapigou Mine The mine is located in the Great Fa Fa Fa River. Ore hardness f = 8 ~ 12; natural rest angle θ = 38 ~ 40 °; specific gravity 2.8t / m ~ 3; loose coefficient of 1.6. The mine uses deep underground mining, there are four production Hang Hau, up to shaft depth of 56m, double-well double cans double cage upgrades, is a medium-sized mine, has been mining for more than 160 years.
