FIELD: drilling technology in mining industry. SUBSTANCE: this relates to producing of minerals and particularly to producing of liquid fuel. One of object of invention is assembly used for realization of bore-hole drilling. Assembly has head part of bore-hole installed above common bore-hole, first and second tubular links seated in bore-hole, and facilities for separation and supporting first and second pipes arranged on head part of bore-hole. Second object of invention is creation of assembly of bore-hole head part which has first facility for separation and supporting of at least two pipes located within limits of common bore-hole. Second facility is intended for supporting of at least two production casing pipes passing in separate underground bore-holes. One of production casing pipes passes through one of pipes, and second production casing pipe goes down through another pipe. Third object of invention is method of drilling and equipping of underground bore-holes. According to this method, two separate pipes are suspended from head part of bore-hole and arranged within common bore-hole. First underground bore-hole is drilled through one of two pipes. First production casing pipe is secured in head part, it passes through first bore-hole and is supported in head part of bore-hole for ensuring delivery of liquid medium from underground formation. EFFECT: higher efficiency. 29 cl, 16 dwg
