The invention discloses a pre-buried double-pipe stepping type goaf nitrogen injection method which comprises the following steps: firstly, determining the length of an oxidation heating zone of a goaf, enabling the oxidation heating zone to move forwards along with the recovery of a fully mechanized coal mining face, and laying two nitrogen injection pipes in front of and behind a whole recovery air inlet roadway, namely a first nitrogen injection pipe and a second nitrogen injection pipe. The two nitrogen injection pipes are respectively connected with a nitrogen injection source through valves outside a mining stopping line of a working face, and the two nitrogen injection pipes move forwards to oxidize a heating zone to perform double-pipe stepping type nitrogen injection along with pushing mining of the working face, so that the spontaneous combustion phenomenon of residual coal in a goaf can be avoided, the fire extinguishing effect is achieved, and the purpose of preventing and extinguishing fire is achieved. Smooth operation of a coal face is guaranteed, the safety coefficient of coal mining operation is improved, two pipelines are directly buried at a time, stepping alternating type nitrogen injection is carried out, and the problems that a conventional nitrogen injection pipeline is difficult to install and recycle, prone to breakage and short in working time are solved.
