History
From 1866 to 1914 50 000 miners dug the hole with picks and shovels, yielding 2 722 kg of diamonds. The Big Hole has a surface of 17 hectares and is 463 metres wide. It was excavated to a depth of 240 m but then partially infilled with debris reducing its depth to about 215 m; since then it has accumulated water to a depth of 40 m leaving 175 m visible. The underground Kimberly Mine was mined to a depth of 1097 metres.
There is currently an effort in progress to register the Big Hole as a World Heritage Site[1]
Not the biggest
In 2005, Steve Lunderstedt, reported after doing intensive research he discovered that it was actually not the biggest hand-made excavation.
By studying historical records of several man-made mines, he discovered that the title belongs to the Jagersfontein Mine.
He claims a comparison between the Big Hole and other mines were never made and it was just assumed to be the biggest and used as selling point for tourist attraction.[2]
