深凹金属露天矿破碎站移设步距与周期的研究

Research on Moving Increment and Period of crusher in Depression Metallic Open Pit

在采用汽车—半移动破碎—胶带半连续开拓运输方式的深凹金属露天矿中,由于其矿体赋存条件、剥采顺序的复杂性,确定破碎站移设的步距与周期变得十分困难。以设计某矿山为例,应用单位成本最小理论,建立了成本计算数学模型,并采用计算机编程的方法求出了最优解,取得了满意的效果。对生产实际有非常重要的指导意义,从而探索出一种深凹金属露天矿破碎站移设步距与周期的计算方法。

In the depression metallic open pit which adopts the semi-continuous transportation of truck-senti mobile crusher-beh,it is very difficult to determine the moving increment and period of crusher, because the complexity of existence of ore body and mining sequence. Took a mine designing for example, after adopted the theory of minimutn unit cost, set up the cost calculate model and solved by computer,the best result was found. It is important for guiding production, and a calculation method for moving increment and period of crusher was found.
