摘要
在煤田地质勘探组织施工时,需要明确钻探目的层位深度、煤层厚度、采样井位及煤层层位、样品煤质化验项目。因钻遇煤层较多、采样层位变化较大、煤质化验项目较多等原因,常用的Excel与AutoCAD技术记录、展示、查询、修改设计数据工作量巨大,难以满足现代勘探施工需求。使用ArcGIS平台建立空间数据库,可实时准确地管理煤田地质勘探中地质数据,以图形化方式展示地质信息,为项目管理人员提供可视化的高效率的信息服务。ArcGIS还可灵活制作复杂的点、线、面图元,批量绘制地质图件,可以自动形成等值线图件,并能智能化计算煤层储量。ArcGIS空间数据库技术是一种创新的数据管理方式,可以在煤田勘探中推广使用。
During the organization and construction of coalfield geological exploration,it is necessary to clarify the depth of drilling target horizon depth,coal seam thickness,sampling well location,coal seam horizon and sample coal quality test items.Due to many coal seams,large changes in sampling horizon and many coal quality test items,the workload of common excel and AutoCAD technology recording,displaying,querying and modifying design data is huge,which is difficult to meet the needs of modern exploration and construction.The ArcGIS platform is used to establish a spatial database to manage the geological data in coal field geological exploration in real time and accurately,display the geological information in a graphical way,and provide visual and efficient information services for project managers.ArcGIS can also flexibly make complex point,line and surface primitives,draw geological maps in batches,automatically form isoline maps,and intelligently calculate coal seam reserves.ArcGIS spatial database technology is an innovative data management method,which can be popularized and used in coalfield exploration.
