Being knowledgeable about rock properties is vital to being effective in the design of blasts in mines, quarries and other construction projects. Without proper knowledge, the energy released during blasting can be underutilized, harm the environment, and may escalate costs. Rock Engineering Design: Properties and Applications of Sound Level aids scientists and practicing engineers in determining rock properties in a quick and precise way. It presents the basic concepts and principles on which sound level can be used in solving rock engineering design problems.
Highlighting the importance of sound level in determining rock properties, the book focuses on the indirect method with emphasis on the development of numerical models in rock engineering design.
- Discusses determining rock property using sound levels produced during drilling
- Explores the benefits of effective rock design applications
- Helps students to develop an interest in using sound level as a tool in rock design applications
The book provides a general introduction to noise, its effect, and standards. It discusses the application of noise monitoring for mining equipment, the application of acoustic emission techniques in geotechnical fields, the equipment for drilling, measurement of sound, and the physico-mechanical properties of rocks. It also explores the process involved in the measurement of rock properties and sound level. This book summarizes in tables and figures the statistical values of the rock properties and sound level produced during the drilling of different rocks. It explains developed regression models, procedure, and the results of developed artificial neural network models. Rock Engineering Design: Properties and Applications of Sound Level includes a case study, and offers a summary and suggestions for further work.

"…the authors appear to be onto something which, once its practical aspects can be exploited in the field, certainly has the potential for effective use in predominantly large-scale mining or extractive operations."

"Selection of topics are well arranged, readers may follow the topic easily in a logical way without losing interest. …The application of sound level in determining the fault and its diagnosis in the mechanical industries is very well known technique for practicing engineers and scientists. However, its application in rock engineering design is not very common and this book is unique in the market in this respect and I believe it will open new horizons to students and scientists working in rock engineering. … The topic of the book is a new area in the field of rock mechanics and I believe it will open new horizons to research students and practicing engineers. …"

"…Applying a novel concept, the authors have demonstrated that rock properties can be estimated to a reasonable degree of accuracy even without carrying out actual tests in some established laboratory. The suggested method can be used for preliminary estimates of rock properties, thereby saving time and cost. … I am of the opinion that the authors have presented a new idea through this book. This idea may prompt researchers worldwide to carry out further research in this area."

"Few of the numerous textbooks published on rock mechanics and mining engineering stray from the core subject matters of index properties, mass parameters, and ground stress. This book is very different - not only does it address a non-core subject but it makes it the centrepiece of the book. The fundamental premise presented here is that acoustic emissions (AE), or the sound generated by the mechanised drilling of rock, can be used to indirectly determine other rock properties such as strength."
