Method of developing CBM fields comprising drilling a vertical well, of planting the vertical wellbore below the producing coalbed not less than 50 m, collaring horizontal wells on the estimated distance from the locations of the vertical well, which is drilled wellbore vertically, then it is bent, discloses productive coal seam passes through a productive formation with the intersection already drilled barrel main vertical borehole, a horizontal borehole then cased and cemented to the producing coal seam roofing submersible pump for pumping produced water is run on a column of tubing in a vertical well bore and disposed in the sump, characterized in that a horizontal wellbore is drilled at a negative bias towards the vertical well.
