Uncovering the Secrets of Britain's Underground Mining Industry
ScienceEarth SciencesJoin Natasha and Debbie as they delve into the fascinating world of underground mining in the UK. From the discovery of polyhalite to the construction of hidden mines, this video provides an in-depth look at this innovative industry.
The Polyhalite Discovery
⛏️The UK is the only country in the world mining polyhalite.
⚗️Polyhalite does not require chemical treatment after mining.
🌱Polyhalite is a fertilizer that is a solution for high value crop nutrition problems.
Building the Hidden Mine
🏗️The mine is designed to be hidden and accessed through a service shaft enclosed in a massive barn.
🚧The tunnel is 5m in diameter with 20cm thick concrete walls.
⛑️The shaft is lined with steel reinforced concrete walls and has a winding tower for lifting workers and equipment.
FAQ
What is polyhalite and why is it important?
Polyhalite is a natural fertilizer that provides essential nutrients to high value crops without the need for chemical treatment. It is important for sustainable agriculture and crop nutrition.
How is the underground mine accessed?
The mine is accessed through a service shaft enclosed in a massive barn, with steel reinforced concrete walls and a winding tower for lifting workers and equipment.
What are the long-term implications of underground mining?
The video raises questions about the management of underground caverns and the concept of leaving the landscape and cities above ground intact while extracting resources underground.
How is polyhalite extracted from the mine?
The mine will use tunnel boring machines (TBMs) to excavate the tunnel, with each TBM weighing 2,000 tons and progressing at an average rate of 20m per day.
When will the mine start exporting polyhalite?
The mine is expected to start exporting millions of tons of polyhalite per year in 2027.
