Description
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.
