Research status and development trend of disaster risk prevention and control of tailings pond
Tailings pond is formed by the accumulation of tailings,which is a dangerous source of high potential energy.Once the dam breaks,it may pose a serious threat to the safety of downstream residents and facilities,and it is very likely to cause serious accidents.Based on the collection of a large number of research literatures related to tailings pond disaster risk,this article introduces the research status and achievements of tailings dam stability analysis and instability mechanism,tailings pond safety monitoring technology,tailings pond disaster risk identification,and tailings pond disaster risk assessment and disaster warning,and points out the shortcomings of the current research:1)the dynamic multi-factor coupling mechanism of tailings dam throughout its life cycle has not yet been clarified;2)The high-precision monitoring technology of the tailings dam needs to be further studied,and the safety monitoring index system needs to be further improved;3)The tailings pond disaster risk identification has not yet introduced intelligent algorithms,combined with multi-source data such as three-dimensional big data system and surrounding environmental information;4)Multi-source data fusion analysis has not yet been considered for disaster warning of tailings ponds.By discussing the current problems of tailings pond disaster risk prevention and control in China,and putting forward development suggestions,the paper provides a reference for the theoretical research and technological innovation of tailings pond disaster prevention and mitigation.
