Abstract：Exploration and development of the coal-bed methane (CBM) is very important to economics, environment and society. It is a key factor to trace and assess the process of the coal-bed gas mining dynamically for its efficient development. In the present article, based on the theory of natural resources super low frequency (SLF) electromagnetic detecting, the method that uses the SLF to trace the coal-bed gas mining dynamic is introduced. The field tests in 2007 and 2010 in the QIN-Shui basin, Shanxi province of China indicate that this method is efficient for the dynamic of the coal-bed gas mining.
