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

Hu Yongquan (Maanshan Institute of Mining Research)  
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.
