| Abstract: | A new concept and technique was developed to reinforce roadway in soft rock by combining external roof bolting with internal grouting. This technique was successfully applied to a roadway in soft rock under dynamic pressure caused by mining in Qishan Mine. The FLAC program,which is currently universally employed in rock analysis in the world ,was introduced to investigate its mechanism. It is of important significance to theory and technique of rock bolting of roadway in soft rock in China. |
