摘要: 为了解决无底柱分段崩落法采矿中损失贫化大的问题,通过数值模拟,对崩落体形成过程进行了模拟,确定了崩落体的外部形态,并通过放矿过程中对颗粒位移监测的方式进行了矿岩移动规律研究。研究结果对指导矿山生产具有很强的实际意义。

Abstract: In order to solve the problem of high loss and dilution of ore by using the pillar-less sublevel caving method, the formation of caving body is numerical simulated, the shape of caving body is determined. The moving laws of the internal ore-rock of caving body is studied by monitoring particle displacement in the ore drawing process.The study results of the paper has strong guiding significance for the actual production of mine.
