Abstract: Based on the Chen Silou mine 16 mining auxiliary lane tunneling along the fault, and soft coal roadway roof and broken, can't normal construction of tunneling technology and supporting plan, after searching technology innovation, short dig short branch technology from practice, optimizing the construction organization, eliminate the safety hidden trouble,Through the observation of roof abscission layer, effect is remarkable. For soft and broken coal seam of the mine roadway excavation and supporting provides a new train of thought.

Key words: soft and broken, short dig short branch, supporting parameters, strengthen the supporting
