: The book is designed for field use. It prioritizes safety, risk management, and ethical engineering practices over dense mathematical derivations. Verdict
: The text explicitly differentiates between active support (intended to immediately stabilize the rock mass) and passive support (designed to react to ground movement), providing practical context for modern ground control. Practical tunnel construction
: Unlike many texts that focus solely on machines, this book emphasizes how geological mediums—both rock and soil—dictate every other decision in a project, including method selection, productivity, and required ground support. : The book is designed for field use
