Abstract: It is crucial to promote coal mine water disaster prevention and control from information to intelligent transformation for ensuring the coal industry high quality development. This study was conducted to meet the multiple demands of coal mine water hazard intelligent prevention and control. Thus,some technologies including cloud computing,big data,artificial intelligence were introduced. In addition,in terms of the technical problems including low comprehensive management efficiency of coal mine water disaster data,lack of precision in advance prevention and control of water disaster,low timeliness of flood emergency decision making and difficulties in identifying flood accidents,the main technical methods of coal mine water hazard intelligent prevention and control were analyzed. Besides,the authors have developed a series of new technologies including coal mine water disaster big data management,dynamic fine construction of mine 3D geological model,coal mine water hazard analysis and evaluation and advanced prevention digital system and computer aided diagnosis of post disaster accidents. Then,some corresponding systems have been developed successfully. They include the coal mine water disaster big data management system based on multi source information fusion,the dynamic fine modeling system of 3D geological body in coal mining,the coal mine water hazard analysis and evaluation and advanced prevention digital system,the flood accident emergency response remote auxiliary system and the flood accident remote diagnosis and analysis system. Ultimately,the authors have established an intelligent prevention and control platform for preventing and controlling coal mine water hazard and applied in coal mine sites. This platform has improved the digital and intelligent technology level of coal mine water disaster prevention and control in advance,disaster management and post disaster diagnosis. The research results will promote the progress of coal mine water hazard control technology in China. It can provide support for coal enterprises to carry out basic data management and water disaster assessment and prevention,and industry experts and national safety supervision departments to carry out decision making for flood emergency responses and accident diagnosis. At the same time,it is also an important support for the digitalization of traditional water damage control technology and intelligent transformation.
