After confirming the existence of a coal mine beneath this area.
Lei Wenjun's team used instruments like polarimeters to roughly measure the reserves of the underground coal mine.
Finally, a preliminary conclusion was reached.
The size of this coal mine is about 4 square kilometers, the coal seam is not very thick, and it is classified as a small coal mine.
The geological reserves of the entire coal mine are approximately 11 million tons, with exploitable reserves between 5 to 7 million tons.
Don't be misled by the figure of five million tons seeming quite large.
In reality.
Such reserves are considered insignificant in the coal mining field.
On Earth, there are many large coal mines with reserves in the tens of billions of tons, domestically alone there are over 1,300 mines with hundreds of millions of tons—in Jin Province, coal mines with exploitable reserves less than 2 million tons are deemed barren mines!
