冶山铁矿北矿区下部矿体矿岩稳定性数值模拟

Numerical Simulation of Ore-rock stability of Lower Orebody in North Mining Area of Yeshan Iron Mine

根据冶山铁矿北矿区下部矿体具体赋存条件 ,采用岩石力学中三维有限元法对目前开采空区稳定状况、深部矿体开采预留矿柱方案进行计算分析 ,确定合理的矿柱结构形式 。

In view of the occurrence conditions of the lower orebody in the north mining area of Yeshan Iron Mine,three dimensional finite element methods in rock mechanics was used to calculate and analyse the stability of the present mined area and the scheme of pillar preservation mining for deep orebody,and determine the rational pillar structure type,providing reference to lower ovebody mining and ground pressure control.
