The invention discloses an underground empty roadway passing method, slurry and a roadway, relates to the field of excavation, and aims to solve the technical problem that the safety of constructors is seriously threatened by an empty roadway passing method. According to the underground empty roadway passing method, when the working face of the roadway is located at the first working face target position, the first distance is formed between the first working face target position and the empty roadway, at least one first drill hole is formed in the position, close to the top and the bottom, of the working face respectively, and the first drill holes communicate with the empty roadway and the roadway; a plurality of sets of second drill holes are formed in the working face from the top position to the bottom position, in the direction from the roadway to the empty roadway, at least one set of second drill holes are drill holes extending upwards in an inclined mode, and at least one set of second drill holes ar
