Underground Ringhole Blasting

By Kaushik Dey, Vivek Kumar Himanshu, Ashish Kumar Vishwakarma

This comprehensive technical guide examines ringhole blasting methodologies in underground metalliferous mining operations. It systematically addresses the scientific principles, engineering design fundamentals, and classification of underground mining techniques. The book covers rock blasting theory in confined environments, detailed blast design protocols, and practical applications across diverse rock mass conditions. Special emphasis is placed on virgin mine operations, ore recovery optimization, dilution control, and the management of challenging geological conditions.

Provides a comprehensive breakdown of ringhole blast design parameters, supported by practical design examples and guidelines. Covers burden optimization in both narrow and wide ore bodies, incorporating stope geometry and rock mass characteristics. Discusses practical adaptations of ringhole blasting in geologically challenging conditions, including design modifications to mitigate hanging wall instability and unplanned dilution. Examines how stope parameters, such as height, width, and orebody dip angle, affect ore dilution. Includes comparative analyses and international case studies related to ringhole blasting.

This book is intended for graduate students, researchers, and professionals in mining engineering, mine blasting, mine design, and mining operations.
