With the recent years, China's natural disasters and mine safety accidents occur frequently, casualties and economic losses caused by the hinder China's development and progress. Especially mine safety accidents, complexity and sinister, in a certain extent, also hindered the work of the command of the rescue workers. How fast and accurate implementation of the rescue operations, is an important problem to be solved in China. Therefore, the author in the coal mines use symmetric digital subscriber loop (Symmetric Digital Subscriber Line, SDSL) multimedia technology, designed to improve the level of China's mine accident rescue.
