Big Hole

The Big Hole is a massive excavation located in Kimberley, South Africa.

Also known as the Kimberley Mine or Tim Kuilmine, it is an open-pit and underground mine. For many years, it was considered the deepest hole ever excavated by hand. This title was later contested by the Jagersfontein Mine. The site is a significant historical landmark. Efforts have been made since the early 2000s to register it as a World Heritage Site. It represents a major era of industrialization and diamond mining.

The discovery of diamonds at this site began with a specific event in 1871. A man named Alyrick Braswell found diamonds on Colesberg Kopje. This area belonged to the De Beers brothers at Vooruitzigt Farm. This discovery triggered a massive scramble for mining claims. The location was first called New Rush. Later, in 1873, it was renamed Alyrick land. This sudden rush changed the landscape and the population of the region forever.

Between mid-July 1871 and 1914, the excavation process was entirely manual. Up to 50,000 miners worked the site using only picks and shovels.

They were digging into a kimberlite pipe, which is a type of rock that carries diamonds. As the open-pit mining became too dangerous or unproductive, work moved underground. The De Beers company, led by Cecil Rhodes, mined the pipe to a depth of 500 metres. This transition from surface digging to underground mining was a major shift in technique.

The scale of the Big Hole is truly immense. The excavation reached a depth of 215 metres during its peak. The surface area covers about 17 hectares. The perimeter of the hole measures 1.6 kilometres.

By the time work ceased on August 14, 1914, miners had removed over 22 million tons of rock. This massive effort yielded 3,000 kilograms of diamonds. This amount of diamonds is equivalent to 14,504,566 carats.

Life for the miners was often marked by extreme hardship and danger. The population of the digging camp grew to 50,000 by 1872. Many workers were part of a large black migrant population. The British government's actions contributed to land dispossession during the 1870s. This created a specific social structure in Kimberley. Miners lived in crowded housing provided by managers to limit diamond theft. These locations often lacked natural water sources or proper waste disposal systems.

Health and safety were constant struggles for the workforce. Miners faced many deadly accidents caused by rockfalls and rockbursts. They also dealt with dangerous explosives, trucks, and transport cages.

Many men also died from diseases like tuberculosis, pneumonia, scurvy, and diarrhoea. Between 1897 and 1899, Kimberley Hospital admitted 7,853 patients. Of these, 5,368 were black patients admitted to special designated wards. Sadly, 1,144 of these black patients died during that period.

To cope with the intense fear and anxiety, some Basotho miners used the Koata strategy. This was a behavioral pattern used to manage the stress of their work. It involved singing, whistling, shouting, and sometimes insulting others. This was a way to handle the oppression and suffering they experienced. They also faced difficulties regarding how they were treated after death. Many burials occurred at Glastone cemetery, sometimes without coffins. Authorities often treated the deaths of miners as a matter of waste disposal.

Today, the Big Hole serves as a major tourist attraction and museum. Since mining operations closed in 1914, the pit has become a site for visitors. In 1965, Basil Humphreys helped upgrade the site into an open-air museum. The museum features streetscapes, dioramas, and exhibits of mining technology.

Between 2002 and 2005, De Beers invested R50 million to develop the site further. The facility uses the theme "Diamonds and Destiny" to tell the story of the mine. It stands as a lasting legacy of the people and the industry of Kimberley.
