Mine Information System Based on 3D Geological Modeling

The nature geological features of mine, such as ore body, terrane, cracked belt caused by rupture, and tunnel, goaf, etc., are one real 3D dynamic geography and geologic environment. The production and organization activity of mine are all in real 3D environment. It is essential that utilizing the computer-based digitization technology to model all kinds of geologic conditions and paroxysmal accident encountering in the mining and digging course. Building 3D geological model, it is of far reaching importance for the design and construction during the process of mine building, for the dynamic management of numerous and jumbled engineering geology material during excavating production and administrative procedure, for improving the data visualization degree, for advancing work efficiency greatly, and for safety in production of mine. The concept of digital strata is proposed to solve such problems. Based on the aim above, that is to build the mine information system, we design the system frame. From the bottom data management to higher level of analyses and application, the frame is divided into four layers: data management layer, model layer, spatial analysis layer, and application layer.
