Abstract

The article describes numerical modeling of sublevel stoping using the discrete element method. The study included development of a modeling procedure, creation and calibration of the numerical models, and the result analysis. The optimal design parameters of structural components of the mining system are found, which are promotive of reduced ore losses in sublevel stoping at the Khibiny apatite–nepheline deposits. Some behavioral patterns of rock mass during sublevel stoping are obtained. The mechanism of ore losses is described.

基于dem的分段回采矿石损失分析

摘要本文介绍了采用离散元法进行分段回采的数值模拟。该研究包括建模程序的开发、数值模型的创建和校准以及结果分析。找出了采矿系统结构部件的优化设计参数，有利于降低希比尼磷灰石-霞石矿床分段回采时的失矿率。得到了分段回采过程中岩体的一些行为模式。阐述了矿石损失的机理。
