Solar power offers many advantages to the energy-intensive mining industry. Its modular design allows panels to be moved as the mine expands, sunshine is free and generating the electricity produces zero carbon emissions. For these reasons alone, industry experts expect to see a boom in solar energy use at remote mines in the near future.
One of the essential aspects of the planning stage of mining activities is how the land will be rehabilitated once the ore has been extracted. Increasingly, mine reclamation and restoration plans are required for a mining permit to even be granted. Creating useful landscapes that meet a variety of goals, ranging from the restoration of productive ecosystems to the creation of industrial and municipal resources, is the key aim of mine reclamation projects and essential to burgeoning sustainability initiatives.
Some of the earliest tunnels date back to around the 22nd century BC, when the Babylonians started using underground passageways for irrigation. Between 2180 and 2160 BC, they successfully dug a 900-metre-long tunnel under the Euphrates River. It wasn’t until 1867 that tunnel building truly boomed as this was when Alfred Nobel patented dynamite. Pictured here at a remarkable length of 24.51 kilometres is the Lærdal Tunnel in Norway, the world’s longest finished road tunnel.
The term tommyknocker originated in Cornwall, UK, where superstitious miners believed goblins lived inside the mines. These supernatural creatures were believed to knock on the walls to alert the miners that something was about to happen. The knocks were usually seen as a portent of impending death, but some optimistic miners believed it meant they were about to strike it rich.
Sandvik Mining and Rock Technology recognizes the need to recycle steel and cemented carbide and as such has implemented a comprehensive recycling programme that benefits customers as well as the company. By recycling drill bits containing steel and cemented carbide, energy consumption is reduced by around 75 percent compared with using virgin materials, which reduces CO2 emissions by around 40 percent. In addition, NOX emissions are also reduced and the use of hazardous chemicals virtually eliminated. So not only can customers do their part for the environment, but they can also minimize costs and reduce waste.
One of the first legends with origins in Cornwall is the superstition about red-haired women. In general, women in or near a mine are considered bad luck in many cultures, most probably because women historically only ever descended into the mines in times of tragedy. Seeing a red-haired woman on your way to work at a mine was an especially bad omen, as she was considered a portent of imminent death.
In some parts of the world, mining can still be a hazardous business. The mines around Potosi, in Bolivia, are believed to have claimed the lives of as many as 9 million people over three centuries of colonial mining. These days, conditions have improved but risks remain. As a result, workers pray to El Tio (the uncle), lord of the underworld. This demonic spirit is believed to be fond of sweet treats, alcohol, cigarettes and coca leaves, which are showered over altars of his likeness by those requesting his protection.
The High Five — about to be executed perfectly by these Sandvik Mining and Rock Technology colleagues — is an internationally renowned way to say “great job!”. Collaboration is important; acknowledging great collaboration even more so. And April 18 is international High Five Day, so make sure to celebrate with a friend.

Walls of salt, 250 million years old and 35 metres high, dwarf a Sandvik LH621 loader at esco – european salt company’s mine in Bernburg, Germany.
Before modern-day quarries even conceived of loaders, there was the Blondin. This high-wire contraption was a type of ropeway used in open-pit quarries in Wales. It was named for Charles “The Great” Blondin, a famous French tightrope walker from the 19th century. Blondin became famous for crossing Niagara Falls at the US-Canadian border on a tightrope suspended 50 metres above the water many times, once even sitting down halfway, cooking and eating an omelette.
Asteroid mining is quickly becoming a reality. Companies such as Planetary Resources and Deep Space Industries are searching for cost-efficient ways to mine large asteroidal specimens and excavate the precious resources within, the yields of which are estimated in the trillions of dollars. Asteroids are replete with platinum, nickel, cobalt and water, which can be broken down into fuel, solving one of the great problems of space exploration: fuel availability.
Outside of Velardeña in northern Mexico, a 30-million-tonne zinc deposit is breathing new life into the area.
Government controlled alcohol sales in Sweden started with miners. At copper mines in Falun, alcohol-related accidents and fatalities had risen to disturbing levels. Mine owners petitioned to form a distribution company with exclusive rights to build distilleries and sell liquor. The end result was a state organization whose job involved regulating all alcohol sales in the city, safely and responsibly.
The Berkeley Pit, a former open-pit mine, is now a man-made lake that contains more than 150 billion litres of toxic water. The water is heavily acidic and has taken on an almost blood-red colour from the copper and iron deposits. It looks like one of those places devoid of life entirely, but it’s not; it is home to a new species of fungi that could lead to important advances in modern medicine.
