Abstract: Based on the engineering background of 6m high mining face in a mine, the support design of flexible die concrete along goaf is carried out. Focus on the design of roadway support parameters and floor reinforcement parameters, temporary strengthening supporting parameters. The engineering practice shows that the support parameters of the flexible mode concrete along the empty side of the 6m high mining face are reasonable and the effect is good, and has good economic benefit and application prospect.
