根据伊什坦贝尔德金矿所在国家的特点、矿体开采技术条件,开发了以壁式崩落法为主,结合削壁充填法和全面法工艺特点的壁式削壁崩落采矿法,对该矿倾斜软弱破碎极薄矿体进行分采。试验结果表明,该法回采率达到91.56%、贫化率仅13.73%,综合生产能力42.3 t/a,采矿成本58.89元/t,为倾斜极薄软破矿体的高效安全开采提供了一个新思路。
According to the characteristics of the country where ISTANBELD gold is located and the technical conditions of orebody mining, a wall-type caving and caving method, which is mainly wall caving method combined with wall filling method and comprehensive process technology, has been developed to tilt the mine Weakly crushed very thin ore body for mining. The test results show that the recovery rate of the method reaches 91.56%, the depletion rate is only 13.73%, the comprehensive production capacity is 42.3 t / a, and the mining cost is 58.89 yuan / t, providing a new and efficient safe mining for the sloping ultra-soft soft- Ideas.
