Abstract :
The spatial database of coal bed methane (CBM) is established on the analysis of data about CBM in Hancheng mining area. the relationship between the content of methane and main structure line, the radius of buffer area for structure control of gas is confirmed, the storing layer is divided into three parts: seepage district, and blocked and vaporized district by the buffer analysis of the area. With the spliced analysis of coal thickness, content of methane, coal depth, coal construction and close function of roof and floor structure condition, the CBM exploitation of main coal seam is divided into advantageous, disadvantageous and common area. Finally it points out the target area of exploitation.
