The invention discloses a super-long working face double-measure roadway arrangement method under the sequential mining condition. The super-long working face double-measure roadway arrangement method under the sequential mining condition comprises the following steps that a first gob-side roadway and a first measure roadway are tunneled on a working face of a next section in the current stoping working face stoping process; a connection roadway is tunneled, wherein the connection roadway is tunneled from the first gob-side roadway to the first measure roadway; extending the connection roadway to a design position of a second measure roadway; tunneling the second measure roadway; finishing excavation of a second gob-side roadway after the current stoping working face finishes stoping and the gob stably sinks; and closing the connection roadway, the first measure roadway and the second measure roadway before the working face of the next section is stoped to the roadway intersection. The super-long working face
