The invention provides a superhigh-water material filled working face gangue pumping gob-side entry non-pillar mining method. The method specifically comprises the steps of establishing a superhigh-water material filling system and a mine gangue pumping and filling system respectively; excavating a haulage roadway and a track roadway and forming a cutting hole in a mining area to form a complete first mining working face; conducting mining on the mining working face according to the normal working procedures; conducting backfilling on a mined goaf through a superhigh-water material; conductingfilling on the portion, where the roadway needs to be reserved close to the working face, of the goaf by pumping gangue filling bodies; after completion of filling, reserving the track roadway as thetrack roadway of a next working face, and excavating a new haulage roadway and forming a cutting hole to form a second mining working face; after completion of filling, reserving the haulage roadwayas the haulage roadway of the next working face, and excavating a new track roadway and forming a cutting hole to form a third mining working face, and repeating the steps. Through the superhigh-watermaterial filled working face gangue pumping gob-side entry non-pillar mining method, the strata pressure intensity of the working face is weakened, non-pillar mining is realized, and the mining rateof the mining area is remarkably increased.
