Strata Behavior Laws of Gob-side Entry Retaining During the Secondary Mining Influence Period

Taking the belt roadway in 18207 working face in Tunlan Coal Mine as research object, this paper analyzes the roadway surface displacement of gob-side entry retaining as well as load bearing and deformation laws of filling body beside roadway during secondary mining influence period. The results of the study show that the roof, floor, two walls and filling body of gob-side entry retaining are stable during the secondary mining influence period.
