RR229a - Coal mine roadway support system handbook
The purpose of this Handbook is to provide a useful reference for European Mining Engineers who wish to obtain unbiased comparative information on the more innovative support systems that have become available in Europe in recent years. As such it does not include details of arch type supports and tends to concentrate on rock reinforcement systems and their related accessories. Where possible the Handbook provides information on the history of application, results of testing and appropriate applications for the various support systems. Also, in most cases it includes photographs of the systems, to help in identification and understanding their construction, and information on how the system's performance can be properly monitored underground.
