【摘要】：为了满足矿山精细化管理的要求,实现生产的安全性和高效性目标,针对地下金属矿山传统计划编制时存在主观性强、实时性差、效率低、误差大以及难以求得全局最优解的弊端,以采掘车间月出矿量、月出矿平均品位、月生产利润为目标,以采场地质条件、车间生产能力、生产任务以及生产原则为约束,构建基于多目标0-1规划的采掘车间作业计划优化模型。模型采用理想点法对目标函数进行降维,决策变量为二维0-1变量,从空间和时间2个维度描述了采掘车间的生产决策状态,简化了模型的求解过程,在LINGO求解器中编写模型语言进行求解,进而得到计划周期内的最优排产方案。以某地下黄金矿山车间作业计划编制为应用案例,解算出某月采场开采的最优时序方案,并用甘特图进行直观展示。结果表明:该模型适用于地下金属矿山采掘作业计划编制,克服了手工编制方法的弊端,保证了采掘车间生产指标的动态平衡,有利于提高矿山的经济效益。
[Abstract]:In order to meet the requirements of mine fine management and realize the goal of safety and high efficiency in production, the traditional plan of underground metal mine is characterized by strong subjectivity, poor real time and low efficiency. The disadvantages of large errors and difficulty in finding the global optimal solution are that the monthly ore output, the average grade and the monthly production profit of the mining workshop are taken as the targets, and the geological conditions of the stope, the production capacity of the workshop, the production task and the production principle are taken as the constraints. The optimization model of mining workshop job plan based on multi-objective 0-1 planning is constructed. The model adopts ideal point method to reduce the dimension of the objective function, and the decision variable is 2-D 0-1 variable. The production decision state of mining workshop is described from two dimensions of space and time, and the solving process of the model is simplified. The model language is written in the LINGO solver to solve the problem, and the optimal scheduling scheme is obtained in the planning cycle. Based on the working plan of a underground gold mine workshop as an application case, the optimal timing scheme of a certain month's stope mining is solved, and the Gantt diagram is used to show it intuitively. The results show that the model is suitable for mining operation planning in underground metal mines. It overcomes the drawback of manual compilation method, ensures the dynamic balance of production index in mining workshop, and helps to improve the economic benefit of mines.
