Current Situation of CBM Developments in China and One Example-Feasibility Study of Surface CBM Well in Hebi Coal Mine Area in China

摘要

As an alternative energy source,methane has been developed commercially in America.But it is just in the first stage in China.Especially for Soft plus low permeability coal seam,there are still questions about whether the technology is mature or not.So there is no precedent of ground drainage of this type of seam.Now,we have made exact ground drainage design for this type of seam and provide solution to drainage technology difficulties.
