1 矿山生产概况 姜家窑金矿设计生产规模为200t/d,该矿有一个坑口为地下开采,竖井井筒直径φ=3.5m,井深244m,绞车型号为2JK—2/20,采用双层单罐笼带平衡锤提升,井下开拓4个中段,深度至-80m。 为确保矿山的持续稳定生产,该矿决定进行深部开拓。根据地质报告提交勘探结果,-80m～-255m标高的范围内地质储量为473501t,品位4.91g/t,金属量2323.314kg。根据该矿体赋存条件,初步设计采用盲竖井开拓方案,盲竖井深175m,井筒为3.3x2.8m2的矩形断面,选用2JT1600/824绞车,电动机功率95kW,设计提升能力140t/d,采用2号单层罐笼带平衡锤提升,钢丝绳罐道。该井作为深部开拓主要提升井,担负矿石、设备、人员和材料等运送任务,下设-115m、-150m、-185m、-220m、-255m5个生产中段。
1 mine production profile Jiang Jiayao gold mine design and production scale of 200t / d, the mine has a pit for underground mining, shaft diameter φ = 3.5m, depth of 244m, winch model 2JK-2/20, with double single Cages with counterbalance to enhance the underground development of four mid-depth to -80m. In order to ensure the sustained and steady production of mines, the mine decided to carry out deep exploration. According to the geological report submitted to the exploration results, geological reserves within the range of -80m ~ -255m elevation of 473501t, grade 4.91g / t, the amount of metal 2323.314kg. According to the ore deposit conditions, the blind shaft was initially designed with a blind shaft depth of 175m and a wellbore of 3.3x2.8m2. The 2JT1600 / 824 winch was selected with a motor power of 95kW and an designed lifting capacity of 140t / d using 2 Single-layer cage with counterbalance lifting, wire rope tank Road. The well, as the main open pit for deep exploration, is responsible for the transportation tasks of ore, equipment, personnel and materials. It has -115m, -150m, -185m, -220m and -255m5 production sections.
