... Abstract Existing rock mass classification systems, such as rock mass rating (RMR) are often used in many empirical design practices in rock engineering contrasting with their original application, i.e. estimation of TBM performance in various ground conditions. However, the use of RMR...

... Abstract Application of roof bolts to support in developed galleries during underground coal mining is a common practice. Mechanised depillaring (MD) applies these roof bolts to support the galleries at the goaf edge also. Goaf edge of a depillaring panel inherits a number of openings, which...
