分析露天矿道路组成,对露天矿道路的不同路段进行合理划分,划分方法涉及到道路的路面质量、坡度和承载能力等因素,从而完成对露天矿道路的描述。提出露天矿道路网络节点的选取原则及其网络边权值的计算方法。建立起露天矿道路网络模型,设计露天矿道路网络数据库作为道路网络模型的后台数据库支持,数据库中包括网络节点数据表和节点间关系数据表,每个网络节点对应一个路段端点,每个关系对应一条网络边。设计出网络图节点的自动提取程序,并将节点数据信息自动存储到露天矿道路网络数据库中。选择粒子群算法作为道路网络路径的优化算法,实现了求解指定两点间的最短路径的粒子群算法。程序将搜索到的最优路径自动显示到网络图中,并达到了较高的搜索精度。
By analyzing surface mine road components, the surface mine road is reasonably divided into different sections; the road surface quality, slope, bearing capacity, and other factors are used to describe the surface mine road. The calculation method involving selection principle of surface mine road network nodes and the network edge weights is proposed, a surface mine road network model is established. The database of surface mine road network is designed for the background data support of surface mine road network model. In the database, there is a table for the network nodes and also a table for the relationship between the nodes; each node corresponds to a section node, each relation corresponds to a network edge. The extraction procedure to automatically pick up the network diagram node is designed and the information of node data is automatically stored into the surface mine road network database. The Particle Swarm Optimization (PSO) algorithm is selected for the road network path optimization; the PSO involving the shortest path between the specified two points is achieved. The optimal path is automatically displayed on the network diagram with the relative high search precision.
