Abstract
A coal and coalbed methane mining system based on ground drilling includes: a drilling component, a coal mining drill bit and a ground facility group. The coal mining drill bit is set at a predetermined end of a directional borehole in a coal seam, connected to the drilling component through a connecting pipeline. The ground facility group is connected to the drilling component, to provide coal cutting slurry for the coal mining drill bit, receive reflux slurry carrying coal and coalbed methane, and precipitate and separate the reflux slurry carrying the coal and the coalbed methane. A coal and coalbed methane mining method based on ground drilling and related devices are also disclosed.
