摘要
本文以岩石力学理论为基础,应用三维弹塑性节理有限元理论对井筒煤柱的开采进行了理论模拟,特别是井筒煤柱包含断层且井筒穿过断层这样的复杂条件,本文采用了特殊方法(节理单元方法)进行了研究,在井筒煤柱开采方面有了进一步的认识.
In this paper, a three-dimension elas-plastic joint finite Element theory is used to simulate the dieting of shaft coal column based on rock mech -anies. Especially the complex condition which the shaft coal column includes fault A special method (Joint element method) is used to study the question in the paper. The work of the paper gains a deeper understanding of shaft coal column mining.
