Abstract: The anchor grouting technique is a kind of sublimate of anchorage support,It makes the surrounding rock to form a wholethrough groutingand then to anchorage,It can improve the ability of resistance to deformation of surrounding rock,and solve the low roadway surrounding rock strength, breakage and the problem of large deformation.Taking a mine roadway in shanxi as an example, it was adopted in conjunction with anchoring and grouting support,Effectively solved the problem of roadway stability and deformation,It fully proved that the anchor grouting support is a roadway support technology which can control the deformation effectively, and has great potential.
