THE STUDY OF OPTIMIZED STRUCTURAL PARAMETER OF DEEP MINING STOPE IN JINCHUAN LONGSHOU MINE

To enhance the comprehensive productivity of deep part zone and apply large-scale mining equipment in LONGSHOU mine,we choose the difference simulated scheme and use the method of three-dimensional numerical simulation.According to the actual condition of LONGSHOU mine,we optimized structural parameter by building eight kinds of three-dimensional entity model adopted the down hexagon drift.So we have obtained the optimum scheme by analysing the change law of safety factor,displacement and the stress of various simulated schemes,and offered the theory basis for further mining optimization production.
