Research and Application of Full-Length Grouted Anchor in Roadway under Mining Face

Abstract:

According to the difficult support problems of the roadway under the coal face on Dongtan Mine in China, a new reinforcing method using full-length grouted anchor is put forward. The strengthening principles are analyzed firstly, and the designing parameters are determined. At last the field construction is done in the north crosscut. The results show that the deformation is small and the roadway becomes stable. The good technical and economic results are obtained by the actual application.
