摘要
提出锚杆与注浆有机结合加固软岩巷道的思路,发明了外锚内注式新型锚杆及其加固软岩巷道新技术,成功地将该技术用于旗山矿软岩动压巷道的加固工程,采用目前国际岩土工程分析通用的FLAC程序对锚注支护机理进行了研究。
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.
