The invention discloses a fault testing method for reflection method channel wave seismic exploration roadway advanced detection. The fault testing method comprises the following steps of establishing a reflection method channel wave seismic advanced detection system, performing detection testing, analyzing a single-shot record result, processing multiple-shot record superposed data, and determining a fault position. The fault testing method is advantages in that reflective wave method channel wave seismic technology is utilized for detecting a structure in front of a blind roadway and is novel in China; the structure which is in front of the roadway and is separated from the roadway by a longest distance of 200m and has a least fault throw of one half coal thickness can be detected in advance; the structures at two sides of the roadway in a range of 200m can be detected; the fault testing method is a new approach for finding out new facilities and new methods for blind roadway advanced detection; and furthermore the method ensures safe tunneling of the roadway in which a limestone water disaster occurs because of an unknown fault.
