Paperback. Condition: New. 2023 ed. 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.

Taschenbuch. Condition: Neu. Neuware -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.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 168 pp. Englisch.
