Join 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.
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.
