Research And Application Of Tailings Pond Safety Early Warning Based On Meteorological Forecast

With the development of industrialization,the mining of ores has become more and more frequent,and the mining process has produced a large amount of industrial waste.Due to the current technical limitations,these wastes cannot be fully utilized.These wastes contain a large amount of metal or non-metallic ores,such as abandoned wilderness.It will cause serious environmental pollution and resource loss.Therefore,it is necessary to use tailings ponds for precipitation and accumulation,and secondary utilization will be carried out when the technology is mature.The so-called tailings pond is usually established by way of enclosure and damming to intercept the mouth of the valley.The main purpose is to store ore waste after mining and screening.In order to ensure the safety of tailings ponds,in recent years,online monitoring systems have been widely used in tailings ponds to monitor tailings ponds in real time.Real-time monitoring such as clarification distance cannot deal with the overtopping and dam collapse disasters caused by continuous heavy rainfall due to special meteorological conditions.The reason is that the online monitoring system does not have the function of forecasting and forecasting.When an emergency crisis occurs in the tailings pond,people do not have enough time to respond to the disaster,which is likely to cause major life safety and financial losses.By studying the flood discharge models of dams in the water conservancy,reservoir and tailings pond industries,this paper finds out the variation patterns of the discharge flow,flood peak flow and flood discharge flow of the tailings pond under different conditions,and establishes a tailings pond flood discharge model to simulate the tailings pond discharge.Flood discharge capacity.According to the tailings pond early warning platform to obtain the next 72 hours,48 hours,24 hours,6 hours of rainfall data,build the FAHP priority relationship matrix based on this,and then use the fuzzy analytic hierarchy process to evaluate the safety of the tailings pond in real time.If the result is any level of yellow,orange,or red,it means that there is a potential safety hazard in the tailings pond and it is necessary to send an early warning message to the administrator as soon as possible.This topic strengthens the comprehensive safety assessment of tailings ponds under various extreme weather,develops key technologies for the safe operation of tailings ponds in metal mines,and establishes a tailings pond safety early warning platform that integrates online early warning and comprehensive evaluation...
