Abstract: Based on the full analysis of the present situation at home and abroad,this paper puts forward the concept and core content of transparent mine and five principles to be followed in constructing transparent mine. Based on the latest development of spatial information technology,the paper expounds the architecture of transparent mine system in- cluding three-dimensional engine layer,intelligent coal mine platform layer and production operation layer,and intro- duced the solutions of the key technical problems of three-dimensional spatial modeling criterion for coal mine,the storage and integration of multi-source spatial-temporal data,the construction and dynamic modification of high-preci- sion geological models,the three-dimensional visualization of massive data,and mechanical and electrical equipment modeling and simulation and three-dimensional automated remote control. Those establish a solid foundation for trans- parent remote management and control of coal mines. Some technologies have been applied in Yangquan Coal Industry (Group) Co. Ltd.
