摘　　要：狮子山铜矿自20世纪70年代投产以来,矿山的资源状况及开采条件已发生重大变化。通过对矿山当前资源保有情况及开采能力进行分析,结合十八中段以下资源量控制程度较低的地质实际,应用泰勒公式及产能计算公式确定与矿山实际资源情况相适宜的产能范围(3 000~2 800 t/a),并确定年利润、生产成本、人员劳动生产率及服务年限为主要决策目标。利用熵权法得出各目标的权重系数为0.249 32、0.249 32、0.249 32和0.252 04。结合效果测度综合分析表明,当矿山产能为3 000 t/a的排产结果最优。在线性规划理论的基础上,运用最小品位偏差法及目标函数模型构建产能衔接规划模型,结果表明铜品位为0.48%、确定年产金属量为2 690 t时可满足新主井的提升能力。According to the fact that the resource status and exploration condition of Shizishan copper mine change greatly since 70 ＇ s of last century, this paper calculated the reasonable productivity range （3000 - 2800 tons/year） in accordance with the mine＇ s real resource situation, by using the taylor formula and deliverability cal- culation. In addition, the main decision targets have been determined as annual profit, production cost, labor pro- ductivity and service life. The weight coefficients for each target have been determined as 0. 249 32, 0. 249 32, 0. 249 32 and 0. 252 04 respectively by using entropy weight method. The comprehensive analysis of the effect measurement showed that the production scheduling results achieve the optimal at the mine-annual output value of $ 000 tons/year. On the basis of linear planning theory, the integration planning model of mining productivity has been established by using minimum grade chordal deviation and objective function model. The results indicated that the new planning could meet the hoisting capacity of main shaft at the copper grade value of 0.48% and the annual metal value of 2 690 tons.
