Research on the rapid construction platform of coal mine GIS one-map

摘要: 目前，煤矿使用的工程专题地图基本都是CAD制图，高效提取CAD图件中的数据并快速组织成地理信息系统（GIS）服务，进而支持矿井空间对象创建和业务属性扩展，集成安全生产实时数据，是构建煤矿GIS一张图的关键。基于ArcGIS平台将CAD图件转为GIS服务的方法实现过程较为繁琐，且ArcGIS平台成本较高，无法较好地跨平台运行。针对该问题，设计了一种煤矿GIS一张图快速构建平台。该平台包括CAD图件管理、地图服务发布、专题地图管理3大功能模块：CAD图件管理模块用于图件基础信息管理和状态跟踪，地图服务发布模块用于地图打包发布和在线预览，专题地图管理模块用于地图服务管理、矿井对象创建及属性扩展。基于开放设计联盟（ODA）的Teigha for Java SDK实现CAD图件全要素精确识别与快速准确提取；通过构建基于GIS数据特征的煤矿CAD图件数据分层描述模型，实现了CAD图件全要素数据快速存储；按照面向对象设计思路，开发了Spring Cloud框架下的Web端煤矿CAD图件数据集存储接口及专题地图服务发布平台，实现了煤矿GIS一张图快速构建。以某煤矿采掘工程平面图为例，分别采用传统方法和快速构建平台进行煤矿GIS一张图的构建，对比结果表明，快速构建平台可大幅提高煤矿GIS一张图的构建效率，为煤矿智能化建设提供时空数字底座。

Abstract: Currently, the engineering thematic maps used in coal mines are mostly CAD drawings. Extracting data efficiently from CAD drawings and quickly organizing them into geographic information system (GIS) services, thereby supporting the creation of mine spatial objects and business attribute expansion, integrating real-time safety production data are the key to building a coal mine GIS one-map. The implementation process of converting CAD drawings into GIS services based on the ArcGIS platform is cumbersome. The ArcGIS platform has high costs and cannot run well across platforms. In order to solve the above problems, a coal mine GIS one-map rapid construction platform has been designed. The platform includes three major functional modules: CAD drawing management, map service publishing, and thematic map management. The CAD drawing management module is used for basic information management and status tracking of drawings. The map service publishing module is used for map packaging and online preview. The thematic map management module is used for map service management, mine object creation, and attribute extension. Based on the open design alliance (ODA), the Teigha for Java SDK is used to achieve precise recognition and fast and accurate extraction of all elements in CAD drawings. By constructing a hierarchical description model for coal mine CAD drawing data based on GIS data features, rapid storage of all element data in CAD drawings has been achieved. Following the object-oriented design approach, a web-based coal mine CAD drawing dataset storage interface and thematic map service publishing platform are developed under the Spring Cloud framework, achieving rapid construction of coal mine GIS one-map. Taking the mining engineering plan of a certain coal mine as an example, traditional methods and fast construction platforms are used to construct coal mine GIS one-map. The comparison results show that the fast construction platform can significantly improve the efficiency of constructing coal mine GIS one-map, providing a spatiotemporal digital base for the intelligent construction of coal mines. -
