Abstract: Based on the current situation of 3107 working face in Xinyuan Company of Yangquan Coal Industry, this paper put
forward and analyzed support technologies at retaining roadways along goaf in high gas outburst seam in 3107 air-return roadway,
namely, support strengthening technologies and solutions of 3107 air-return roadway, roof support technologies and solutions
above filling area, filling body supporting strengthening technologies and solutions, supporting strengthening technologies and
solutions of retaining roadways along goaf, and then pointed out that their effects are good at in reducing tunneling quantity and
improving recovery rate and working surface preparation time.

Key words: gas coal seams；soft surrounding rock；retaining roadways along goaf；support technology
