Abstract

Abstract: The failure probability of tailings dam， evolution simulation of sand flow downstream of dam break， the loss of life ，the life loss risk acceptable criteria of the tailings dam break， and the best safety investment to save lives were studied. The tailings dam slope failure function and the personal life acceptable risk criteria of tailings dam break were established. Taking a tailings dam as an example， a case study was carried out. The optimal safety investment for life saving was calculated to be 3.9 million RMB. Compared the standard of the United States with China′s current industrial injury death compensation， it is suggested that the relevant departments of our country should improve the compensation standard for work-related injuries.

Key words: tailings dam, life loss, risk control, Monte Carlo, LQI(life quality index)
