A new dynamic test facility has been established by the Western Australian School of Mines in Kalgoorlie. The facility uses the principle of ‘momentum transfer’ to dynamically load rock reinforcement systems and assess their suitability for use in rock burst ...

The Swiss Alptransit System (also called NEAT) is an important element of the new European high speed railway network . This system, which is currently under construction, consists of two railway axes - the Gotthard and Lštschberg Axes - which will pass through ...

The RMi (rock mass index) system applies input of block size, joint characteristics and strength of intact rock to express the uniaxial compressive strength of a rock mass. From practical use in more than 5 years the RMi rock support method has been further ...

The RMi system is based on def,rned inherent rock mass parameters. Basically, it combines the compressive strength of intact rock and a jointing parameter (JP) in the expression RMi :JP represents the main jointing features, namely block volume (or density ...

<p>Rock support is the term widely used to describe the procedures and materials used to improve the stability and maintain the load bearing capacity of rock near to the boundaries of an underground excavation. In this paper, a distinction is drawn between ...
