There are a number of factors in the installation process which may have an influence on the performance of the Swellex bolt.
Although the grouted bolts are generally suitable for use in most types of rock mass,expansion bolting still accounts for a significant share of underground mine workings,this is mainly due to tha simplicity of installation and the resultant higher bolting performance.
This study aimed to evaluate and optimize the design and application of cable bolts to ensure safety and efficacy in geotechnical engineering.
Laboratory pull-out tests were conducted on the following rock bolts and cable bolts: steel rebars, smooth steel bars, fiberglass reinforced polymer threaded bolts, flexible cable bolts, IR5/IN special cable bolts and Mini-cage cable bolts.
Rock bolts used for the reinforcement of underground mines, tunnels, and nuclear waste repositories are made up of low and medium-carbon steels, and high-strength low alloy steels.
The deformation or failure morphology and analysis of rock bolt in practical applications.
