时空数据模型在露天矿排产中的应用

Application of Spatio-temporal Data Model in the Mining Scheduling for Strip Mines

针对露天矿开采数据具有的时空特征,在现有的时空数据模型的基础上,采用了面向对象时空数据模型来组织露天矿开采时空数据,以动态规划和0-1整数规划相结合的算法对露天矿进行排产,并以马钢和尚桥露天矿为例,建立时空数据库保存规划结果。在形成有历史、现时和计划数据的时空数据库的基础上实现露天矿规划排产系统的设计及应用开发。

In light of the characteristic of the spatio-temporal data of strip mining and based on the existing spatio- temporal data model, the object-oriented spatio-temporal data modeling was used to organize the spatio-temporal data of strip mining and make the strip mining scheduling by an arithmetic integrating dynamic programming and 0-1 integer programming. Taking He Shang Qiao Open-pit Mine of MaSted as an example, a spatio-temporal database was setup to store the planning results, It was based on the spatio-temporal database with historical, present and planning data that the design and application development for the mining scheduling of strip mines were made.
