应用分形理论研究螺旋切削采集法截割富钴结壳粒度分布规律 ,结果表明 ,其粒度分布具有很好的分形结构 ,可以用分形维数定量描述。通过大量试验 ,初步测定截割破碎富钴结壳及其模拟料粒度分布的分形维数在 2 .4 2 36～ 2 .6 112之间 ,提出了切削深度与粒度分布关系的回归模型 ,用于预测截割破碎富钴结壳的情况 。
Fractal theory is used to study the granularity distribution law of the broken cobalt-rich crust collected by spiral cutting. The result shows that its granularity distribution has a very good fractal structure and can be quantitively described with fractal dimension. Through a large number of tests, it is preliminerily determined that the fractal dimension of the granularity distribution of broken crust by cutting and its simulation material is between 2.4236～ 2.6112. A regression model for the relationship between the cutting depth and granularity distribution is proposed to predict the result of cobalt-rich crust cutting and improve the design of deep sea-bed mining system.
