金属非金属尾矿库安全现状及分析

Analysis of current safety situation of metal and non-metal tailing pond

2003年至2004年,国家安全生产监督管理总局组织了金属非金属尾矿库安全状况的调查, 调查了2692座代表性的尾矿库。在被调查的尾矿库中,正常库有643座,占23．9％;经过正规设计的有1253座,占43．9％;定期进行过风险评价的206座,占7．7％;且很多尾矿库下游是高密集人员集聚区,一旦发生溃坝事故,将造成重大人员伤亡和财产损失。我国尾矿库安全状况令人担忧。

From 2003 to 2004, State Administration of Work Safety has made an investigation on safety situation of metal and nonmetal tailing pond. 2692 representative tailing ponds have been researched. 643 tailing ponds which constitute 23.9% are safe; 1253 tailing ponds which constitute 43.9% are designed regularly; 206 tailing ponds which represent 7.7 % accept risk assessment periodically. Some dense population districtare situated at downstream of the tailing pond. And once these tailing dams break, heavy loss in personnel and property will happen inevitably. The safety situation of tailing pond in China is alarming.
