Abstract

Abstract: According to the "ThreeSoft" roadway under dynamic pressure of Fenghui Mining is hard to support,the reason of the emerge of advancing abutment press is studied by analysis of the movement of surrounding rock .The scope of advancing abutment press is obtained by date recorded in roadway. Analysis of influence factors of deformation of roadway show that deformation of roadway is caused by the coupling of surrounding properties and advancing abutment press.The countermeasure of supporting is that the Supporting intensity is able to control the deformation of roadway and Release the energy of deformation when it passing through high stress range. support scheme is Putting forward base on the countermeasure. Numerical simulation show that deformation of roadway can be well controlled.
