【Abstract】 In order to adapt to the gob side entry retaining in the high cutting working face,the support design of flexible formwork concrete gob side entry retaining is carried out at 6 m high cutting working face in Huoer Xinhe Coal Mine. The parameters of road-side support,floor reinforcement parameters and temporary strengthening support parameters are mainly designed and studied. The results show that the support parameters of flexible formwork concrete for gob side entry retaining in the working face are reasonable,and the effect is favorable,providing good economic benefits and application prospects.更多还原
