Ground Vibrations From Tunnel Blasting In Granite

This text describes topics discussed at the conference, including: tunnelling and construction in soft ground and rocks; geological investigations; tunnelling machines; planning for underground infrastructure; safety issues and environmental and social aspects of underground development.

This book is a unique supplement to contemporary scientific literature on rock blasting technology. It encapsulates theoretical and practical aspects of drilling and blasting techniques used in both surface and subterranean excavations connected with civil as well as mining activities. Case studies are presented to illustrate correlations between theoretical calculations and empirical findings. It also summarizes the results of research carried out by the Blasting Department of the Central Mining Research Institute since its inception in the year 1970. It contains fifteen extensive chapters covering statistical methods, design parameters, rock breakage mechanism, structural damage, fragmentation, emerging techniques, surface and sub-surface blasting methodologies, safety and environmental aspects, explosive characteristics and modern initiating devices.

This Bureau of Mines publication reviews the research conducted under a 3-year, $6.6 million program in rock mechanics and rapid excavation. The program was sponsored by the Defense Department's Advanced Research Projects Agency and was managed by the Bureau. In addition to the rock mechanics investigations, projects were funded in the following general areas of rapid excavation: System analysis, geologic prediction, rock disintegration, ground support, and materials handling. This report briefly summarizes the significant technical accomplishments of the individual research projects and references the contract reports and other publicatons where more detailed descriptions of the research can be obtained.
