Book Review

Groundwater control in karst mining has always been a major challenge, with sudden water and mud inrushes posing serious risks. This book focuses on innovative solutions for such problems, using the Chengmenshan copper mine as a case study. It introduces a novel approach to slurry curtain formation, combining traditional engineering methods with the creative use of local materials.

Readers will discover how lake mud can be transformed into a high-performance paste slurry, how its properties can be tailored to specific mining conditions, and how the resulting slurry curtain can effectively manage large underground caverns. Through a combination of field studies, experimental research, and practical engineering insights, this book presents a comprehensive guide to modern groundwater control techniques in complex karst environments.

Key highlights include:

Hydrogeological Analysis and Feasibility: Investigation of the Chengmenshan mine revealed key groundwater control requirements, leading to the proposal of a lake mud paste-slurry and grouting wall method. The design targets include:
Innovative use of local materials for sustainable engineering
A new methodology for large-cavern water control
Integration of scientific research with practical field application

This work provides both engineers and researchers with a unique perspective on solving real-world challenges in mining, blending theory, experimentation, and hands-on solutions in a way that is both accessible and informative.
