The book presents theoretical and practical aspects of Blast Designing for both surface and underground mine excavations. This book embodies the recent research developments in the field of blasting. A number of case studies have been includes to supplement the theoretical aspects of the blast design with the practical ones. Special emphasis has been laid on designing of large production blast-mass blast- which is soon becoming the need of hour in the present mining scenario. The book contains 13 chapters covering basic principles of blast process, selection of blast materials, deciding blast parameters, basic fundamentals of generation and control of ground vibrations, air over pressure and flyrock. Every aspect of the blast design has been demonstrated by a case study-in case of open cast- as Rampura Agucha Lead- Zinc-, Kudremukh Iron Ore-, Jayant Coal- mines, etc. Beside the India's largest underground pillar blast consuming 145t of explosive at Zawarmines has been presented. The main feature of the book is that the Authors- practicing mining engineers have-themselves designed a number od blasts for more than a quarter of century and offered guidelines. The book will equip the readers with latest techniques of blat design balanced with theoretical and practical aspects of it.
