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。
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.
