This book summarizes the advances in mine hydrogeology in terms of the development of new technologies and sustainable mining to prevent water inrush disasters during coal-mine construction and production in China. It presents holistic topics that balance safe coal mining and the minimization of impacts on the environment and human beings. Systematically describing the methods and techniques used in China’s coal mines to predict, prevent and mitigate water inrushes, it includes nine case studies to illustrate the practical engineering solutions using state-of-art methods and technologies under various conditions. It also discusses how the approaches could help solve the world’s water problems, not only in mining, but also in tunneling, disposing of nuclear waste, storing natural gas, and sequestering CO2, as well as their impact on mining industries and related fields around the world. The book intended for students, researchers and practitioners working in the mining industries.

This book comprehensively documents the various types of karst collapse and related conceptual site models, before discussing these collapses in terms of their impacts on engineering and the environment. Featuring over 200 real-world photos to illustrate the variety of karst collapses and their consequences, the book also provides specific methods and techniques to prevent, investigate, monitor and remediate these collapses. Decades of experience with these collapses make it clear that addressing the related hazards requires a multi-disciplinary approach that integrates geomorphology, engineering geology, hydrology, hydrogeology, biology, geophysics, geochemistry, and risk assessment.

This book addresses geohazards by establishing their unique hydrogeological conceptual site models. Geohazards occur in many forms and scales either naturally or induced by human''s activities. Many geohazards such as earth fissure, ground collapse and subsidence, mine water inrush, and groundwater contamination are closely related to hydrogeological conditions and their dynamics. Water, either surface water or groundwater, acts as a resource and an enabling agent that elevates geohazard risks in areas that are inherently vulnerable. The book presents case studies to describe identification and investigation methods, monitoring and early-warning techniques, modeling approaches, and engineering measures to prevent, control, and mitigate these geohazards. It targets students, researchers, practitioners, and decision makers who are engaged in water resource management, project planning, and geohazard control and management.

This book compiles a broad range of monitoring and early warning technologies focused on high-resolution in-situ water quality parameters at springs and monitoring wells. The surface collapses often cause severe damage to infrastructures, properties, and loss of lives, whereas contaminated groundwater poses risks to human health and the environment. Collapses are critical in karst systems, sparsing a seventh of Earth’s land surface. Karsts are also very relevant for drinking water, yet karst represents a fourth of global drinking water. Mitigating collapses and contaminated groundwater in karst aquifers can be complicated and costly.

These parameters detect hydrodynamics, internal soil erosion, and ground deformation changes as karst collapse and pollution proxies. This book represents the most comprehensive overview of decades of research on karst collapse and groundwater contamination.

This book is of interest to researchers and policymakers.
