Top 10 amazing holes in the Earth

In man's search for mineral wealth, many enormous holes have been dug. In addition, nature occasionally produces some astounding holes. This list is a pick of the ten most spectacular natural or manmade holes in the face of the earth.

人类在挖矿石时经常会挖掘出非常巨大的矿洞，此外，自然界有时会形成令人惊叹壮观的洞穴，以下是美国媒体列举的地球表面最壮观的自然或人为洞穴。

1. Darvaza Gas Crater-Turkmenistan 土库曼斯坦达尔瓦扎天然气坑洞

In 1971, geologists discovered a massive underground deposit of natural gas on this site. Whilst excavating the hole to tap the gas, thedrilling rig collapsed leaving a massive hole. To prevent poisonous gasses from escaping, the hole was allowed to burn. It continues to burn to this day and has done so without ceasing.

1971 年，地质学家发现该区域蕴藏着大量的地下天然气，在常年的开采过程中，由于不慎出现钻探环状坍塌，从而形成了一个非常大的坑洞。为了防止有毒气体溢出，土库曼斯坦政府允许对坑洞中的天然气进行燃烧，这个坑洞从白天到晚上一直处于熊熊烈火燃烧状态。因此，这处燃烧的天然气坑洞也被人们称为 “地狱之门”。

2. Kimberley Diamond Mine-South Africa 南非金伯利钻石矿坑
