摘要: 研究了分段充填采矿法的动力学原理。针对右江河地区铁矿的开采条件,设计了4种分段开采方案,利用有限元分析软件ANSYS模拟分析了覆岩及副井在分段采矿时的移动及破坏过程。结果表明:在定配比充填体情况下,4种开采方案副井和覆岩都是安全的。

Abstract: The dynamics principle of the sublevel mining method was investigated.Four sublevel mining programs were designed for the mining conditions of Youjiang river area.The movement and the failure process in sublevel mining of the overlying rocks and the shaft were simulated by the finite element analysis software ANSYS.The results showed that in the case of the fixed backfill mixture,the shaft and the overlying rocks in four mining programs were all in safety.

Key words: Sublevel mining method, Dynamics, Stope stability
