【摘要】：露天矿长远排土规划能够合理规划剥离物排弃位置、指导露天矿短期排土设计,降低剥离物运距,提高运输、排土设备生产效率,显著降低露天矿生产成本,具有重要的理论意义及工程应用价值。根据露天矿采场及排土场发展时空关系,合理简化了露天矿长远排土规划问题,分析了排土场动态调整约束条件,以剥离物总运输成本最小为目标,建立了内排条件下露天矿长远排土规划模型,提出了模型的求解思路并给出了算法流程。定义了模型基础数据,并提出了其计算方法。采用微积分的思想并根据插值、空间几何、运筹学等理论方法提出了算法中的关键问题的求解方法,包括确定排弃阶段位置、计算实体切割后的质心及体积、计算排弃阶段高度、确定运输路径。以扎哈淖尔露天煤矿为例,建立了扎哈淖尔露天煤矿各个地层顶底板的DTM模型以及采场块体模型与排土场块体模型,并进一步根据块体模型获取了扎哈淖尔露天煤矿长远排土规划模型求解所需的数据。在模型基础数据和算法流程基础上,调用3DMine VBA接口编写了求解程序。对扎哈淖尔露天煤矿长远排土规划模型计算结果分析表明,模型计算结果能够指导露天矿合理利用排土空间。
[Abstract]:The long-term drainage planning of open-pit mine can reasonably plan the position of stripping disposal, guide the short-term drainage design of open-pit mine, reduce the distance of exfoliation, improve the production efficiency of transportation and drainage equipment, and significantly reduce the production cost of open-pit mine. It has important theoretical significance and engineering application value. According to the space-time relationship of the development of open-pit stope and dump, the long-term drainage planning problem of open-pit mine is reasonably simplified, and the dynamic adjustment and constraint conditions of the dump are analyzed, with the aim of minimizing the total transportation cost of exfoliation. In this paper, the long-term drainage planning model of open-pit mine under the condition of inner drainage is established, and the solution idea of the model is put forward, and the algorithm flow chart is given. The basic data of the model is defined and its calculation method is put forward. Based on the theory of interpolation, space geometry, operation research and so on, the method of solving the key problems in the algorithm is presented by using the idea of calculus, including determining the position of abandonment stage and calculating the center of mass and volume of the entity after cutting. Calculate the height of abandonment phase and determine the transportation route. Taking Zahanaoer opencast coal mine as an example, the DTM model of top and floor, stope block model and dump block model of each stratum in Zhanaoer opencast coal mine are established. According to the block model, the data needed to solve the long-term drainage planning model of Zahannur opencast coal mine are obtained. On the basis of model basic data and algorithm flow, the solution program is written by calling 3DMine VBA interface. The calculation results of long-term drainage planning model in Zahanaoer opencast coal mine show that the calculation results of the model can guide the rational utilization of drainage space in open-pit mines.
