Restudy on digital mine:characteristics, framework and key technologies

摘要

Based on analysing the problems associated with the promotion of mine digitization in China, the basic characteristics of a digital mine (DM) are described with respect to an intelligent transportation system: high speed intranet as the road-net; modular mining software as the vehicle; mine data and models as the fuel; 3D geoscience modelling (3DGM) and data mining as the filter; data collection and update as the safeguard, and mine GIS (MGIS) as the scheduler. Based on the four-layered structure of C/S and the work processes in a mine, the fundamental constituent diagram and a network framework of DM are designed. The nine key technologies for the implementation of DM strategy are discussed, which includes the data warehouse in mine; the data mining in mine; real 3DGM and visualization; 3D topological modelling and analysis in mine; modular application software and models; underground rapid positioning and automatic navigation; underground multimedia communication and wireless transmission; intelligent mining robot-groups and the integration of 3S (GIS, GPS, RS), office automation (OA) and command dispatch system (CDS). In addition, the recent progress of 'digital Kailuan' is introduced as an example of DM. 26 refs., 4 figs.
