Research on raster-based modeling technology of three-dimensional mine area

Based on the analysis of mining prospecting and mining data, mine area three-dimensional model includes ground-based model, the exploration line profile model, the scope of mining model, mine body model, mining roadway model, reserve calculation block model and goaf model. This paper presents a kind of mine area modeling technique based on scanned raster images. This technology can collect data and establish three-dimensional model of the mining area rapidly based on “old data”, to realize three-dimensional visualization of the mining area and the dynamic management.
