Disaster-causing mechanism and prevention and control path of different types of coal seam roof water disasters in China

China is the country with the most complicated coal-forming and occurrence conditions in the world. The roof water disaster, caused by the diversity and complexity of the hydrogeological conditions of the coal seam roof, the mutuality and time-varying coupling of the mining overburden fracture field and the seepage field, and the uniqueness and harmfulness of the coal mine roof water inrush, is one of the main mine disasters in China, especially in the western coal mining area. In order to better understand the roof water disaster, promote the existing technology and explore new technologies to prevent and control such mine disasters, based on the comprehensive analysis of the law of roof water disaster accidents in China’s coal mines in recent years and the occurrence conditions, water inrush mode, dynamic characteristics and mechanical behavior of roof water-filled aquifers, the types and characteristics of roof water disasters are systematically divided. The disaster mechanism of the main categories and th
