Numerical value analysis of coal bed methane influent equation

ZHANG Li 1,GUO Yong-yi 2, WU Shi-yao 2, ZHANG Xing-zhou 2, LIN Jin-tai 2(1 China University of Mining and Technology, Xuzhou 221008, China;2 Taiyuan University of Technology,Taiyuan 030024, China)  
The paper established a differential equation of coal bed methane influent. The deviation differential equation of coal bed methane influent was digitally analyzed by difference equation with difference method. The established coal bed methane influent mode can correctly shown the coal bed methane flow law in the coal seam, which would have a certain guidance to the development of low penetration anthracite coal seam in China.
