Abstract：According to the high construction risk, poor airtightness and low speed in the traditional gob-side entry retaining, the 12-308 working face of Shangwan Coal Mine applied the new gob-side entry fast retaining technology, which uses gob-side entry retaining support matching with flexible template concrete pump grouting, and the advancing speed reached 15m/d in a 280?5m long and 3?8m high working face. The technology realized fast retaining of gob-side entry in thick coal seam, satisfying the demand of working face full speed advancement with small deformation of retained roadway.
