| Abstract | Coalbed methane, also known as gas, is a kind of combustible gas stored in the pores of coal seams. When the concentration reaches the industrial standard, coalbed methane is a kind of energy that can be exploited and utilized. For the coalbed methane in the intact coal seam, seismic exploration technology is usually used to explore the storage structure of coalbed methane and estimate the reserves of coalbed methane. In many coal fields in China, a large number of goaf has been produced during the long-term mining of coal resources, and there are also a large number of coalbed methane resources in the goaf. Since the physical property difference between coalbed methaneand air in goaf is completely different from that between coalbed methane and coal in intact coal seam, we cannot continue to use seismic exploration to directly explore coalbed methane in goaf. It is very difficult to find coalbed methane in goaf directly, so we adopt an indirect exploration method. For Qinshui coal field in Shanxi Province with high gas content, semi-airborne transient electromagnetic method is used to detect the unknown goaf quickly and accurately in the study area. Then we use Pseudo-seismic migration imaging technology to transform the collected electromagnetic data to virtual seismic data. According to the migration imaging results of "virtual seismic data", it is found that the goaf in the measured area is incomplete, and the research results indirectly reach the exploration of coalbed methane gas storage structure in the goaf area. |
