Recently, the monograph edited by China Coal Energy Research Institute - "Research on the Laws of Sedimentary Pressure Control in Mines in the Northern Ordos Basin" was officially published by Emergency Management Press. For the first time, this book organically integrates sedimentary geology, hydrogeology, mining rock mechanics and other disciplines. Starting from the sedimentary geological background of the Ordos Jurassic coal basin, it reveals that the overlying sedimentary geological conditions are the cause of large-energy mine earthquakes and rock pressure disasters. Main controlling factors, and proposed the concept of "sedimentary pressure control", which proposed a new concept and evaluation method for the prediction, prediction and prevention of mine rock burst disasters, and effectively promoted the theoretical and technological progress of mine rock burst disaster prevention and control.

The book is divided into seven chapters. Taking the typical mines in the northern part of the Ordos Basin as an example, based on sedimentology, geomechanics and key layer theory, the key layers that mainly control the rock pressure in the mines in the northern Ordos Basin are determined; the key layer sedimentation distribution rules are revealed. The main control effect on mine shock pressure; based on the thin plate theory, a coupling impact intensity discrimination model of sedimentary elements and mine earthquake energy was constructed; based on the law of sedimentary pressure control, it was proposed to use the sedimentary environment, the thickness of the main key layer, and the core recovery rate The mine impact risk assessment method with equal elements is the "impact strength index method", and its accuracy and scientificity have been verified through engineering practice.

This book has outstanding innovation, detailed data, rigorous argumentation and strong practicality. It has been unanimously praised by well-known domestic experts. It is an excellent reading for management, scientific research and technical personnel in the relevant fields of the coal industry to learn from. It is also useful for predicting earthquake disasters, Forecasting and prevention have important guiding significance.
