The recent development of domestic and international research on the field of coal mine safety hedge and emergency rescue was summarized. The construction of six systems in the work safety field in China was discussed. The reasons for that the research group chose system integration platform and designed 3D digitizing mine construction platform project were given. The three system integration platform construction, including personnel positioning system, pressurized air rescue system, and water supply rescue system, the implementation of 3D function, and key 3D GIS technology were introduced. By taking Beijing Haohua Energy Company's Muchengjian coal mine underground safety hedge system as an example, the platform realizes the unified integration of all kinds of underground information system and 3D visual management for a coal mine. It improves the overall linkage and emergency response ability of coal mine safety hedge system, which promotes the development of coal mine enterprise information construction.
