分段碎石胶结充填采场稳定性计算机模拟

为了探索丰山铜矿分段碎石胶结充填法合理的采场结构参数，依据该矿地质条件和矿岩、充填体的力学地质，采用有限单元法建立力学模型，分析采空区周边的应力状态，提出了合理的采空区结构参数，为采场设计提供了参考依据。

COMPUTER SlMULATION OF STOPE STABILITY OFSUBLEVEL STOPING WlTH CEMENTED BROKEN-STONE FILLING

In order to approach the reasonable stope structure parameters of sublevel stopingwith cemented broken-stone filling in Fengshan copper mine,a mechanical model was built upwith limited element method in hight of the geol0gical condition and the mechanical properties ofore/rock and fill mass in the mine to analyse the stress state around mined area so as to advancereasonable structure parameters for mined area,which can serve as referential basis for stope design.
