Everyone knows that miners’ work is tough — but it’s rare to get a glimpse inside a real mine, hundreds of metres underground. Active mines are off-limits to outsiders due to dust, dangerous particles, and strict safety regulations. However, in a few places across Europe, visitors can explore underground tunnels in former mines that have been transformed into museums. Below are some photos from deep inside a black coal mine that’s now open to the public: the Guido Mine, located in Silesia, Poland, some 300–350 metres below the surface (>>>).

The idea behind creating the museum was to present the history of coal mining from the miners’ perspective – their working conditions, the tools they used, and the harsh reality underground. The tour begins in dimly lit corridors, with basic equipment and no conveyors for transporting coal. The areas where miners once broke through coal seams with nearly bare hands were incredibly cramped. To reach them, miners had to kneel or crawl through tight spaces. We learned that a major part of the job, beyond digging, was installing ceiling and wall supports in the emptied chambers and tunnels. Yet these supports were often too weak to ensure safety. When they collapsed under the pressure of the overlying rock, the miners stood no chance.
Due to the low light and strict safety regulations, taking proper long-exposure photos was nearly impossible. I realised this when I briefly fell behind the group and had to descend a staircase to a lower level – with only a small flashlight to guide me. Although all necessary safety precautions were in place, taking one or two photos wasn’t worth the risk of getting lost, even for a moment, or worse – breaking a leg. Fortunately, as we moved into more modern sections of the mine, with power cables and overhead lighting, the conditions improved significantly. The photos you see here were taken in those later, better-lit areas of the mine.

Over time, the equipment used to dig into coal deposits was modernised. However, it was still extremely loud and not particularly safe. The chains used to transmit power to the digging heads and to pull heavy loads along the early automatic conveyors had a tendency to snap. When they did, the force with which they lashed out at nearby workers was deadly – there were cases where miners were cut in half. As technology advanced, the machines became more efficient and safer, but they certainly didn’t become quieter. Methods for supporting ceilings and walls also improved, but the risk of rock and coal falls was never fully eliminated. So even today, when we hear about mining accidents, the cause may not only be natural gas explosions, but also the sheer weight and pressure of the earth, causing rockfalls and the collapse of ceiling supports.

When we returned to our hotel after visiting the Guido mine, I noticed black dust on my clothes. Our miner guide had activated some of the machines to show us how they worked – without even touching coal. He explained that if he had, we would have needed to take a long shower and put all our clothing straight into the washing machine. Beyond the risk of accidents, it’s the dust, particles, and constant noise from the tools that take a lasting toll on miners, often leading to lung diseases and hearing problems.
The machine at the front of the photo is a modern, highly efficient coal-cutting machine. It was designed to be pushed forward gradually as coal is broken off, cleared from the site, and transported to the surface. Though extremely costly – with a price tag of several million euros or dollars – it is also remarkably effective in increasing productivity deep underground.
In Poland, electricity production still relies heavily on coal – both hard coal and lignite (brown coal). While there is much discussion around energy transition, in practice, progress remains slow. It appears likely that coal dependency will continue for at least another decade. A major reason is that Poland has yet to build a single nuclear power plant, and constructing even one is a complex and lengthy process. Still, nuclear energy will be a crucial step if the country is to make any meaningful progress in cutting carbon emissions.
Renewable energy sources, such as wind and solar, are also developing rather modestly in Poland. Despite significant potential, investments remain limited, often slowed by legal barriers or local opposition. It’s important to note that, unlike nuclear power, most renewables do not provide dispatchable energy – that is, energy that can be reliably produced regardless of weather conditions or time of day..
