摘　　要：自然崩落法生产能力大、安全、成本低,同时也是技术含量最高的一种采矿方法。针对黄山铜镍矿30#矿体开展了自然崩落法应用研究,通过工程地质调查、可崩性评价、切割拉底数值模拟等前期大量基础研究,30#矿体自然崩落法工业试验非常成功,已采出矿石47万t,采矿直接成本仅37.55元/t。Natural caving method with large production capacity, good safety and low cost, is an advanced technology among mining methods. In terms of the 30th ore body in Huangshan copper nickel mine, the natural caving method was applied and studied. Through a large amount of previous investigation including engineering geological survey, collapse evaluation, numerical simulation of undercutting, and so on, the industrial test of natural caving method was very successful in the 30th orebody, being extracted ore of 470,000 tons, and direct mining cost of 37.55 RMB/ton.
