Development of coal geological information technologies in China

The history of coalfield geology and mine geology IT applications is over 30 years, which is gaining remarkable achievements. This paper sheds light on the development of geological and surveying spatial management information systems. Specifically, this study proposed the development trend, system structure and function design and sub-systems of the new generation of geological and surveying spatial management information system by benefitting from the recent advancements in computer and spatial information technologies. The sub-systems include the "One Map" online collaborative (2D-GIS) management platform, the geological survey mapping collaborative management system, the integrated service system based on "one map", the three-dimensional dynamic geological model system, the three-dimensional transparent management platform, and water prevention and control information management system. This work is an important foundation to realize the IT information and intelligent management of coal industry. The successful development and application of the new generation of geological and surveying spatial management information system will provide the dynamic data support for the online decision-making of the intelligent coal mining.
