基于FLAC-3D数值模拟采场底部结构设计研究

On the Design of Stope Bottom Structures Based on FLAC 3D Numerical Simulation

摘要: 为实现破碎、易氧化结块、高硫矿体安全、高效回采，对矿块底部结构进行设计研究; 通过数值模拟得出的应力、应变和塑性区指标对底部结构的稳定性进行分析评价; 并提出了矿块回采时，应采用底部结构形式的建议.

Abstract: This paper studies the bottom structure of ore blocks by applying numerical simulation to analyze and evaluate the stability of the bottom structure stability for safe and efficient mining of broken, oxidize and caking, high -sulfur ore body. The suggestion of applying bottom structure in the process of ore blocks mining is put forward.
