This book examines the water resistance capacity of the Upper Ordovician limestone and its feasibility as a water barrier to achieve safe and green mining. Mine water inrush events often occur during coal mine construction and production; they account for a large proportion of the coal mine disasters and accidents in China, second only to gas explosions. As mining depths and mining intensity continue to increase, the hydrogeological conditions encountered are becoming more complex. This book describes in-situ methods designed to test the water resistance of the limestone layer, as well as specific grouting techniques developed to transform this layer into a barrier that can prevent water inrush during mining. The innovative technologies, which were applied and validated in two coal mines, are applicable to other coal mines or any underground engineering works.

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 provides an information fusion model with information fusion theory, geographic information system technology and modern mathematical methods to evaluate the risks of groundwater inrushes from aquifers underlying coal seams. In this new model, the water inrush vulnerable index was calculated with variable weights theory. It overcomes the defect of the traditional vulnerability index method that assumes constant weights for the factors controlling the water inrush. Mine water inrush events often occur during coal mine construction and production; they account for a large proportion of the nation’s coal mine disasters and accidents in China. Between 2005 and 2014, 513 water inrush incidents have occurred with a total loss of 2,753 lives. As mining depths and mining intensity continue to increase, the hydrogeological conditions encountered are becoming more complex. The innovative model presented here was applied to two coal mines in China with proved better results than the traditional vulnerability index method. .

This book targets to earth scientists and engineers, in particular students, researchers, managers, and practitioners, who are interested in mining engineering, environmental engineering, green coal mining, sustainable water resource management, and effective measures to balance mine safety and ecological conservation. In the disciplines of mine hydrogeology and mining engineering, there have always been difficulties in the theoretical interpretation of the changes in the physical and hydraulic characteristics of water resisting strata during coal seam mining. In the past 10 years, the authors studied the relevant contents by using the methods of physical simulation, numerical simulation, field test and mining practice of similar materials, so as to understand the internal relationship between the stratigraphic sedimentary characteristics of the mining area and the occurrence mechanism of mine water disaster. On the premise of analyzing and studying the stratigraphic sedimentary environment in the mining area in detail, it is of great significance for the realization of "coal water" dual resource mining in the mining area to divide the types of roof water disaster in the mining area and study the formation mechanism of mine water disaster caused by different rock formation combinations and mining methods.
