Abstract: The search and visualization of dangerous blocks as an important part of safety management of modern underground mine, has not been solved until now because of various reasons. By adopting the research thinking of the subsystem-global mapping and making the two codes of GeneralBlock and 3DMine available with compatible DXF file, the technology of automatic search and systematical visualization of dangerous blocks of underground mine is studied. It takes the developing tunnels at the level of 255 m and 305 m of zinc polymetallic orebody in Tongkeng mine for example. Firstly, the survey data of structural plane are input into GeneralBlock to calculate and analyze the blocks; and the DXF files including dangerous blocks are output. Secondly, those DXF files are input into 3DMine in order to make the dangerous blocks visualization; and their solid models are saved and input into roadway models in 3DMine for measuring the positions of dangerous blocks precisely. At last, the dangerous blocks in the developing tunnels are made systematical visualization by marking them on red alert. The application results show that 27 movable stable blocks and 1 unstable block are found in the developing tunnels by using this integrated technology. Research results testify that the automatic search and systematical visualization technology of dangerous blocks of underground mine can be achieved successfully, which can be regarded as a reference for safety management, disaster warning and fractures consolidation of underground mine.

Key words: dangerous block, search, systematical visualization, GeneralBlock, 3DMine
