In the last 20 years, we have witnessed a revolution in ground stabilization in both underground and above-ground applications, thanks largely to the widespread adoption of shotcrete as a medium for support. Shotcrete technology continues to evolve and improve as its utilization increases. This volume includes a selection of papers describing recent developments in the evolving field of shotcrete technology, written by a wide range of authors from around the world. The subjects range from mining-related ground control requirements, testing and performance characterization, and durability, to nozzleman education and accreditation requirements.
