滇中大姚铜矿属中生代河湖相沉积型含铜砂岩矿床.矿山设计规模:氧化矿1500吨/日,硫化矿3000吨/日.矿山主要开采对象为1~#矿体,本文论述的对象为该矿体的硫化矿部分,其储量占总储量的98.6%,矿体延深斜长3000米,宽80～460米,中段走向长400～1200米,厚度1～35米,平均12米,平均地质品位1.35%,倾角10～25度.设计选用了有底部结构的空场采矿法,采后尾砂水力充填采空区.
The Dayao Copper Mine in Central Yunnan is a Mesozoic lacustrine sedimentary copper-bearing sandstone deposit, with a design scale of 1,500 tons / day of oxide ore and 3,000 tons of sulphide ore per day.The main mining targets of the mine are ore bodies 1 ~ The object is the sulfide ore part of the ore body, and its reserves account for 98.6% of the total reserves. The orebody is inclined to be 3000 meters in length and 80 to 460 meters in width with a length of 400 to 1,200 meters and an average thickness of 1 to 35 meters The average geological grade is 1.35% and the dip angle is 10 ~ 25 degrees.A design of opencast mining with bottom structure is adopted, and the tailing fill after mining is filled with water.
