摘要
本文介绍了离散元法的基本原理及发展应用概况,概述了离散元软件PFC(Particle flow code)的基本程序,并从矿业工程角度出发,从岩土工程、颗粒分离加工作业等4个方面分类综述了PFC在国内外的应用现状。得出PFC在矿业工程中应用潜力巨大,但限于其本身局限性及现今计算水平,需要做更多的工作来保证模拟的准确性与高效性,最后论述了其在矿物加工领域深入应用的可行性。
The paper introduced the basic principle and application situation of discrete element method,summarized the discrete element software program of PFC,and classifying summarized the application status of PFC in mineral engineering from the four aspects of geotechnical engineering,granular separation processing work,etc.Reached that PFC have a huge potential applicated in mining engineering,and need more work to ensure the accuracy and high efficiency of simulation limited to its limitation and current calculation level,finally discussed the further application feasibility in mineral processing areas detailedly.
