The invention provides a sequential mining working face stoping roadway arrangement method back to a goaf, which comprises the following steps: tunneling a first working face air return crossheading, an open-off cut and a withdrawing channel, and reversely tunneling a first working face transportation crossheading along the open-off cut of the first working face; extending and tunneling a second working face open-off cut from the first working face open-off cut, and reversely tunneling a second working face air return crossheading and a transportation crossheading; cutting hole extension of the second working face and tunneling operation of an air return crossheading are completed before stoping of the first working face, and tunneling operation of a transportation crossheading and a withdrawing channel of the second working face is completed in the stoping process of the first working face; and the steps from S2 to S4 are repeated, and the rest working faces are circularly operated in sequence.
