Other AbstractAffected by the mining of Lugu Iron Mine in the basin,Yanjing valley in Mianning County,Sichuan Province,retained a large number of mine waste slags,it caused many serious debris flow disasters in history, resulting in a large number of people,property losses. In the past,in order to prevent debris flow disaster,the local government built diversion embankment,sand retaining dam and other engineering measures in the valley, these measures can play a certain role in disaster prevention,but it is still difficult to play a effect of radical cure in the face of a large number of loose mine waste slags sources,and so far,it is still necessary to clear the silt in the valley every year. In order to change this situation,under the guidance of circular economy theory,the local government has adopted a new method of disaster prevention to prevent and control debris flow disasters since 2012 by comprehensive utilization of mine waste slags. The specific way of this method is: guided by the government, introduce private capital to establish a sand and gravel integrated processing plant in the Yanjing basin,produce the construction sand and gravel aggregate by using waste slags generated during the mining process of Lugu Iron Mine, at the same time,recovery iron ore powder from waste slags,finally,backfill the waste soil in the production process in the waste slags accumulation field to realize land reclamation and ecological improvement. These measures not only reduce the accumulation of loose sources in Yanjing valley effectively,reduce the risk of local geological hazards,at the same time,it also can generate profits for company,increase the revenue of local government and promote employment for local residents. Using iron ore waste slags to produce sands and gravel materials can also reduce local mining of river sand and gravel indirectly,reduce the damage to the ecological environment of rives,which has played role in multiple effects of reducing disasters,increasing income,and protecting the environment. Such new disaster prevention model based on the concept of circular economy can be greatly extended to other areas affected by mineral waste slags accumulation and serious debris flow disasters.
