数字地质调查系统在西藏驱龙矿区资源量估算中的应用

Application of the digital geological survey system in the estimates of resources of the Qulong ore district,Tibet,China

埋藏于地下的矿产资源形态千差万别,产状复杂多变,数据来源多种多样。如何科学、合理、准确、灵活、高效地估算在一定工程控制条件下的资源量,完成资源量估算的各类图件、报表制作满足不同工作的需求是目前急需解决的问题。将数字地质调查系统技术运用到资源量估算领域是解决问题的有效途径。数字地质调查系统是基于GIS技术并在计算机软硬件支持下,融合计算机图形学、计算机人工智能和数据库技术于一体,实现对多源、海量地学实体数据采集、管理、存储、处理、成图、分析、成果输出等全过程的数据表达,实现了从野外工作到成果汇交的全数字化过程的无缝连接。通过在驱龙矿区的应用,充分体现了系统对多源、海量地学数据进行科学、合理、准确、灵活、高效的处理能力。

The shape of mineral resources buried underground is complex and highly varied and there are a great variety of data sources. The problem that needs to be urgently solved at present is to how to estimate the resources under the control of certain engineering work scientifically, rationally, accurately, flexibly and efficiently and complete various kinds of maps and tables for estimates of resources so as to meet the requirements of different work. The application of the technology of the digital geological survey system in estimates of resources is an effective way for solving the above-mentioned problem. The digital geological survey system is based on the GIS technology, and under the support of the computer software and hardware and by integrating the computer graphics, computer artificial intelligence and database technique, the authors achieved the data expression in the flail process of the collection, management, storage, storage, map-making, analysis and result output of multi-source and enormous data of geoscience data and the seamless connection in the full digitalization process from field work to compilation and submission of results. This application in the Qulong ore district fully embodies the ability of this system to treat multi-source and enormous geoscience data scientifically and with high efficiency.
