This book consists of selected papers presented at the 2nd International Conference on Geotechnical Issues in Energy, Infrastructure and Disaster Management (ICGEID 2024), held on January 19-20, 2024 at IIT, Patna, India. The papers represent the research work in the related fields of underground mining, ground control, mining geotechnics, geo-instrumentation, mine tunneling, and underground structures. It focuses on the latest technology being implemented including artificial intelligence and machine learning applications to solve challenges in mining tunneling and geotechnical structure engineering. It also highlights the state-of-the-art technologies adopted by the civil and mining industry for their commercial as well as environmental benefits. The papers are presented by an international pool of academics, research scientists, and industrial experts and therefore cater to the global audience from the field of underground engineering.

This book presents the principles and practices of rock blasting for underground hard rock mining. It covers a theoretical background of the rock blasting technology and comprehensive case studies on different stages of rock blasting for underground metalliferous mining. It includes the discussions on burn-cut face blasting pattern, slot raise excavation methodology, and ring blasting methods. It further discusses different practical challenges associated with underground blasting, viz. ore dilution, ground vibration, wall instability, etc., and their possible solutions. The book also covers the recent advancements in methodologies to predict blasting outcomes and instrumentations for monitoring rock blasting operations. The book is a useful reference for rock blasting practitioners, mining engineers, professionals, and researchers. It is also a valuable reference for undergraduate and postgraduate students.
