Roof Water Disaster in Coal Mining in Ecologically Fragile Mining Areas

Formation Mechanism and Prevention and Control Measures

By: Yifan Zeng,Zhenzhong Pang,Qiang Wu,Hui Qing Lian,Xin Du

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.

Research on Risk Evaluation Methods of Groundwater Bursting from Aquifers Underlying Coal Seams and Applications to Coalfields of North China

By: Yifan Zeng

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.

Establishment of "Drama" Orientation

Transition of the Research Paradigm of Chinese Dramas in the 1920s and 1930s

By: Zhang Yifan

The “national drama” in China is a historical concept. Grown on longstanding Chinese culture and art, the traditional drama, mainly in the form of “opera”, has been integrated with “drama” of an international background. From the perspective of modern “drama and opera”, this book mainly studies the conditions and research of Chinese traditional drama in the 1920s and 1930s. Instead of analyzing from the viewpoint of literature appreciation or music theory, the author regards the drama as a comprehensive stage art. He attaches special importance to restoring historical scenes and therefore mainly introduces the drama journals and monographs published in that historical period, in order to help readers understand the original state of drama at that time through the records of the witnesses. In particular, this book delivers an insightful view about the evolution of the meaning of “national drama” and “drama”. The book will help scholars and readers understand the meaning and the whole story of the “national drama” concept, and will certainly facilitate the construction of the discipline of Drama and Opera.
