Abstract: The coal mines in the Yonglong mining area are all severely affected by disasters,and are subject to complex engineering geological conditions and various disaster factors,making it difficult to conduct a comprehensive survey and control of water hazards caused by detachment. In order to promote the investigation,verification,and effective treatment of water hazards in the mining area,based on the research results of the formation and disaster mechanism of water hazards in the Yonglong mining area,the distribution of water hazards in the coal mine area was investigated through data investigation,geophysical and geochemical exploration,drilling verification,comprehensive research and other survey methods. After the formation of the coal mining face,during the mining period,and after the mining being completed,preventive measures and treatment measures were proposed to form a technical system for the survey and treatment of water hazards in the coal mine area. So as to enhance the disaster prevention and mitigation capabilities and safety level of mines in Yonglong mining area,and ensure safe and efficient mining.
