Research on directional drilling technology for superimposed “three zones” passing through goaf
Guizhou has a large amount of coal resources, which have been mined for a long period of time, resulting in the formation of a large area of goaf. There is a large amount of coalbed methane resources in the goaf, but the exploitation and utilization rate
