Study on Grouting Support of Secondary Disturbed Roadway
In order to solve the problem of large deformation of roadway surrounding rock under secondary disturbance,the deformation of roadway surrounding rock under the grouting support scheme is analyzed through numerical simulation.After obtaining the best grouting reinforcement scheme,the industrial test is carried out.It is found that the maximum deformation of roadway top and floor is 294 mm,and the maximum displacement of two sides is 417 mm.It can meet the requirements of mine mining and provide a certain basis for the safe mining of secondary disturbance roadway.
