Xuyang Xie · Zhongguo anquan kexue xuebao · 2008
Firstly, the factors affecting the disasters of tailing reservoir are analyzed from the self-safety of tailing reservoir, geological condition, meteorological condition and human action. Secondly, according to the selection principles of pre-warning index and the impact of tailing disasters on downstream people and downstream property, the regional alert index system for tailing reservoir is established, which includes 9 indexes, such as the risk grade of tailing reservoir, topographical slope, geological structure and condition, latest day rainfall, accumulation rainfall of latest five days, mining phenomenon, blasting phenomenon, downstream population and downstream property. Finally, according to the alert grade of tailing reservoir, the value range of each index is defined. The establishment of index system provides basic data for the regional alert of tailing reservoir.
