为了克服露天矿生产计划方案精确求解的困难,提出了一种基于改进遗传算法的开采计划优化方法.首先,利用采选成本、精矿售价、矿石回采率、废石混入率、精矿品位和混入废石品位等技术经济参数构建目标函数,并以年采矿量和年采剥量为约束条件构建模型;其次,通过引入灾变算子对传统遗传算法进行改进,避免算法陷入早熟;最后,通过算法运算结果对比验证所提出的算法的性能.结果表明,所提出的方法能够在约束条件下有效处理露天矿开采计划问题,在较短时间内可找到较优的露天矿开采计划方案.与其他的方法相比,所提出的方法在参数设置、模型构建、运算时间方面都具有较大的优势.
Research on Mining Plan Optimization Based on Improved Genetic Algorithm
In order to overcome the difficulty of accurately solving the production plan of open-pit mines,an optimization method of mining plan based on improved genetic algorithm was proposed.Firstly,the objective function was constructed by using the technical and economic parameters such as mining cost,concentrate price,ore recovery rate,waste rock mixing rate,concentrate grade and mixed waste rock grade,and the model was constructed with annual mining amount and annual stripping amount as constraints.Secondly,the traditional genetic algorithm was improved by introducing the catastrophe operator to avoid the algorithm falling into prematurity.Finally,the performance of the proposed algorithm was verified by comparing the results of the algorithm.The results show that the proposed method can effectively deal with the problem of open-pit mining plan under constraint conditions,and a better open-pit mining plan can be found in a short time.Compared with other methods,the proposed method has great advantages in parameter setting,model construction and operation time.
