Seventeen people were killed.〔Wagener, 1997〕 Late in the afternoon on the day of the failure, a thunderstorm occurred and about 50 mm of rain fell in 30 minutes. When the dam failed, 600 000 m³ of liquid flowed 4 km. The nearest houses were located 300 m downslope of the dam; when the wave of water and tailings reached them, it was 2.5 m high. Seventeen people were killed and there was widespread devastation and environmental damage. Eighty houses were destroyed.〔Niekerk, 2005〕 ==Background== When gold-bearing rock is processed and the gold is extracted, the remaining material is moved to tailings dams as waste, as was the case at the Merriespruit No. 4 facility.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Merriespruit tailings dam disaster」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
