Abstract: For problem of limitation of expansibility and compatibility of Web map because that application of Web map need use some tool provided by the third party to realize graph drawing, the paper proposed an application scheme of Web map of coal mine based on SVG. Taking Web global networking of data of underground personnel position system as example, it introduced application of Web map based on SVG in the system. The actual application showed that the scheme has good effect, which breakthroughs limitation of expansibility and compatibility of Web graph drawing technology and makes Web graph drawing need't use tool of the third party.
