[Explanation] The "predecessor" of Yellowstone National Mine Park is Daye Iron Mine. Its core scenic spot, "Mining and Metallurgical Canyon", was once "Asia's first mining pit".

After more than 100 years of large-scale mining, the Daye Iron Mine has consumed 130 million tons of iron ore reserves, and finally formed the "First Tiankeng in Asia" with a maximum drop of 444 meters and a pit area of ​​1.08 million square meters.

  At that time, we could only live in bungalows. Due to mining reasons, the magnifying artillery can not be used as high-rise buildings. The bungalows were filled with ash everywhere, and all the tiles on the tiles were white ash. As soon as the sun is exposed to the sun, the rocks absorb a lot of heat and release it at night. It is extremely hot at night and it is the environment when it is impossible to sleep.

  [Explanation] By the beginning of this century, its iron ore reserves had been less than 30 million tons, and it was listed as a "crisis mine" by the country.

Faced with the pain of resource depletion and environmental pollution, the miners are looking for a breakthrough in transformation.

Beginning in 1990, Daye Iron Mine began to remediate industrial and mining land and carry out ecological reclamation.

Seeing green through the cracks, breaking through the walls, backfilling and planting green, the mines planted trees from generation to generation, and finally planted ten thousand acres of pagoda tree on the stones.

  How to plant trees on stones? We have failed many times. The tree we planted last year still didn’t exist this year, but that dead tree is a dead sapling. Slowly planted trees died, and it became humus. We started planting There are tasks for trees. We carry the soil on our backs with snakeskin bags, and the soil does not stand on top of it. That's how it is, but slowly and repeatedly, generation after generation of miners go up to plant trees, then This is the result.

  [Explanation] Daye Iron Mine completed the Huangshi National Mine Park covering an area of ​​15 square kilometers in 2005. It officially opened to welcome guests two years later and was rated as a national 4A scenic spot in 2010.

  [Explanation] "The second generation of mine" Liu Yuan is an underground worker. With the completion of the mine park, he took off his miner's uniform and bid farewell to the "four stones in one piece of meat" underground environment full of mud and turned into a cultural tourism Practitioners.

  Because ore resources are mined less and less, we actually know this, so in the future, how our mines should go, we also very much hope that it is a great honor to become a pioneer, first to explore this How should I go, so from what I personally think, I feel very honored.

  After the mine park was built, the corresponding supporting facilities and the residential area of ​​the street have been greatly improved, and the house has been greatly improved. I think the environment is very much like the original. In addition to the mine park, the rehabilitation base is established In the future, the environment of the entire mine was hundreds of times stronger than before.

  [Explanation] Today, through the two-wheel drive of industrial tourism and ecological tourism, Huangshi National Mine Park has formed mining production to provide resources for tourism development, and industrial tourism has enhanced the reputation of mining operations and injects vitality into the sustainable development of century-old mines.

  [Explanation] Yan Hongyong, director of the Huangshi National Mine Park Management Office, introduced that the mine park currently receives nearly 300,000 tourists every year, and in 2019, only the ticket revenue reached 3.07 million yuan.

  The next step of our development is to "go up into the earth". The so-called heaven, we are building some amusement projects around our tiankeng, and entering the earth is to bring tourists down to our well, and feel immersively how steel is. Refined, close experience, how the mining workers work, another one is to bring tourists to the bottom of our pit, now we are looking down at the tiankeng, then in the future we can sit in the well and look up at the tiankeng.
