Residual coal full-mechanized repeated mining method of near-distance inflammable seam gob

The invention provides a residual coal full-mechanized repeated mining method of a near-distance inflammable seam gob, which aims to solve the problem of resource loss, natural inflammation and gas discharge difficulty in mining a near-distance underlying seam above which a tool post gob covers. The method comprises the following steps that: upper coal covering pillars are put when a lower seam is mined; a staggered roadway arrangement method is adopted, i.e. an air inlet transportation roadway is arranged in an underlying seam, and tunneling along with the bottom is performed; an air return transportation roadway is arranged in an upper covering seam, and tunneling along with the top is performed; and a process procedure combining a mode that one upper coal covering pillar is put while mining for twice and a mode that one upper coal covering pillar is put while mining for one time is adopted in a working plane, i.e. when the whole seam is not mined, one upper coal covering pillar is put while mining for twice, and when the whole seam is mined in different layers, one upper coal covering pillar is put while mining for one time. With the adoption of the method, the recycling of residual coal is realized while new seams are mined, so that not only is the non-renewable coal resource saved, but also the service life of a mining well is prolonged, and the resource recycling efficiency is significantly improved.
