Analysis on the Key Technologies of CBM Surface Well Development in Mining Active Areas of China
In the past 20 years, coal bed methane (CBM) surface well technology has made some progress in mining active areas in China, but it still remains at its experimental and study stage, and industrialized and large-scale development has not been achieved. The research of the key technologies, such as the distribution of surface wells, the identification and protection of the high-risk locations of casing damage, the optimization of well structure, and the security monitoring of surface drainage in mining active areas, is the key for CBM surface well development in mining active areas of China.
