危险块体的搜索及显现是现代地下矿山安全管理的重要内容,由于各种原因一直未能得到很好的解决.采用子系统映射全局的研究思路,以DXF兼容性格式文件的方式连通GeneralBlock和3DMine两款软件的应用,对地下矿山危险块体的自动搜索及系统显现集成技术进行了研究.以铜坑矿锌多金属矿体255 m和305 m水平的开拓巷道为工程背景,首先,将结构面调查数据输入GeneralBlock完成块体的分析计算,输出含危险块体的DXF格式文件;其次,将该文件导入3DMine软件,析出危险块体,并保存其实体文件;然后,将实体文件调入至3DMine巷道模型中,对危险块体进行精确定位;最后,对所有危险块体着以红色进行预警,从而实现开拓巷道中危险块体的系统显现.应用表明:利用所研发的集成技术,在255 m和305 m水平开拓巷道内,发现了可移动稳定块体27个,不稳定块体1个,顺利实现了地下矿山危险块体的自动搜索及系统显现.研究成果可为地下矿山的安全管理、灾害预警与裂隙加固等提供基本依据.

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.
