基于MapGIS的巷道地质素描图绘制系统设计与实现

摘要

According to the management business requirement of the metal mining and survey data, the components of roadway geological sketch pictures (RGSP) were analyzed, and the drawing flow of RGSP based on MapGIS and the component modules of the drawing system were designed.The main components of RGSP were essential information, strata information, hydrogeology information, notch groove track information, sample test information.The drawing system of RGSP were composed of eight modules, i.e.data management, coordinate transformation, automatic generation of RGSP template, element drawing, ore-rock type and planar structure, automatic generation of notch groove track, automatic lettering, and generation of integrative RGSP.Then, the object-oriented method was used to analyze the component spatial entities of RGSP and the topological relations of these spatial entities, and the spatial data model and logic model of the drawing system of RGSP were established.Finally, the drawing system of RGSP was realized based on MapGIS platform and component-based development technology, RGSP for Meishan iron mine of Shanghai Baosteel Group Corporation was successfully drawn according to the system.The system provided application basis and practical experience for the information construction of mine geological map.%根据金属矿山地测数据管理业务需求,首先剖析了巷道地质素描图组成要素,设计了基于MapGIS的巷道地质素描图的绘制流程以及绘制系统的组成模块.巷道地质素描图组成要素主要由基本信息、地层信息、构造信息、水文地质信息、刻槽样轨信息与样品化验信息组成.巷道地质素描图绘制系统主要由数据管理、坐标转换、巷道素描图模板自动生成、组成要素绘制、矿岩类型与面状构造、刻槽样轨自动生成、自动注记、巷道综合地质素描图生成等8个模块组成.接着,采用面向对象的方法,分析组成巷道地质素描图空间实体对象及其实体对象之间的拓扑关系,建立了支持巷道地质素描图自动绘制的逻辑与空间数据模型.最后,基于MapGIS平台及其组件式开发技术,实现了巷道地质素描图绘制系统,绘制了上海宝钢集团梅山铁矿巷道地质素描图,取得了良好效果,为矿山地质图件的信息化建设提供了应用的依据和实践经验.
