With the gradual disappearance of shallow resources in China,resource mining has gradually shifted to deep mining.As mining activities have turned to deep minings of more than one thousand meters deep,mining dynamic disasters such as impact ground pressure and earthquakes are occumng even more frequently.The frequency,scale,and degree of damage have all significantly increased,and more than 150 mines across the country are threatened by such dynamic disasters.For example,on October 20,2018,21 people were killed due to the impact of the Longyun Coal Industry on the ground pressure,and the loss made a great impact.Therefore,effective control of and safety protection against mine dynamic disasters such as rock-burst remain a key techni-cal bottleneck that severely restricts the safe development of deep resources.It is urgent to solve the scientific and technical problems in the prediction,control and comprehen-sive prevention of dynamic disasters such as rock-burst in deep mining,and to realize the safety protection and effective control of such dynamic disasters.
Mining dynamic disasters such as rock-burst and mining earthquakes seriously threaten the safety of the mine.During the breeding and inducing processes,factors such as stress and energy ke.ep accumulating,causing the surrounding rock of the stope to reach and even exceed the critical state,so that it ruptures,expands amd evolves into earthquake or disaster.The emergence and evolution processes reflect the co-action process of multiple factors such as overburden and stratum structure,original stress field,mining disturbance,etc.It also reflects the synergy mechanism and state evolu-tion process of multiple physical mechanics fields on multiple spatial scales.
This book aims to study the geological conditions,tectonic conditions,and dynamic basic problems in the incubation,induction,and control of rock-burst disasters in deep mining,from the regional stress field state and disaster correlation,the coupling effect of mining disturbance and regional stress field,and its effects.Starting with evolutionary a-nalysis,through the monitoring and analysis of the change process of regional stress effects under the action of mining disturbances,the structural co-evolution mechanism,force-energy transmission mechanism,and dynamic triggering conditions between the rock and the surrounding area stratum are revealed.The book will further explore the mggering effect of solid tidal stress on mining earthquakes,deepen the understanding of mining earthquakes' inducing and inducing mechanisms,explore new theories and meth-ods for analyzing the coupling effects of mining disturbances and regional stress fields,and provide a theoretical basis for the effective prevention and control of disasters in deep resource mining.
The book wasdrafted at the University of Science and Technology Beijing.At the same time,a large number of experiments and data analysis were carried out at the engi-neering site of the mining enterprise.I would like to extend my sincere gratitude and blessings to the instructor Prof Hongguang Ji.Thanks to Mr.Lei Zhang,Mr.Shuang You,Mr.Peng Xiang and other team members for their help and support.Thanks to the National Natural Science Foundation of China (51534002) ,the Major Scientific and Technological Innovation Projects in Shandong Province (2019SDZY02) ,the Basic Sci-entific Research Business Expenses of Central Universities ( FRF-TP-16-074A1,F(xiàn)RF-TP-19-026A2) ,and the Chinese Postdoctoral Science Foundation (2017M620623) for their great support for the research and publication of this book.At the same time,I would like to thank Ms.Na Yang at the China Building Materials Industry Press,for her excellent work during the typesetting process,and I have benefited greatly communica-ting about the manuscript with her.While writing this book,I read a lot of domestic and foreign literature and peer work,and I thank them for their hard work.
The main content of this book is from my doctoral dissert.ation.It is my first aca-demic professional book.Although I have done a lot of work,due to the limited level,omissions and inadequacies would certainly exist in the contents.Experts and readers are more than welcomed to criticize and correct it.
