Table 2 The life cycle stage and characteristics of the five major open-pit coal mines in China.
From: Impact and elastic modulus of coal mining on terrestrial ecosystems
Name of coal mining area | History of mine construction | Life cycle stage | Ecosystem succession process | Graphical representation |
|---|---|---|---|---|
Inner Mongolia Huolinhe open-pit coal mine | Construction began in September 1981 and production began at the end of August 1984 | In the late stable development stage, the annual production of coal resources basically reached the highest and remained stable. The change from a damaged ecosystem to one that is degraded or severely degraded | The original ecosystem is enhanced to a certain extent by external interference and remains stable, and the damage to the structure and function of the ecosystem continues to accumulate, and the ecosystem becomes a damaged ecosystem. Mining enterprises attach importance to ecological restoration, and take reconstruction/restoration measures to the mined areas, and the damaged ecosystem gradually changes to another balanced state |

Inner Mongolia Yimin open-pit coal mine | Construction of the coal mine began in 1976, and it was put into production in 1985 | In the late stable development stage, the annual production of coal resources basically reached the highest and remained stable. The change from a damaged ecosystem to one that is degraded or severely degraded | The original ecosystem is enhanced to a certain extent by external interference and remains stable, and the damage to the structure and function of the ecosystem continues to accumulate, and the ecosystem becomes a damaged ecosystem. Mining enterprises attach importance to ecological restoration, and take reconstruction/restoration measures to the mined areas, and the damaged ecosystem gradually changes to another balanced state |

Inner Mongolia Yuanbaoshan open-pit coal mine | Construction began in October 1990, trial production began in August 1998, and production was officially handed over in April 2005 | In the early stable development stage, the annual production of coal resources continued to increase. The ecosystem is in a damaged state | The original ecosystem is enhanced by external interference, and the damage to the structure and function of the ecosystem continues to accumulate, and the ecosystem becomes the damaged ecosystem |
|
Inner Mongolia Jungar Wusu open-pit coal mine | Construction began in May 2006, and it was officially put into production in 2008 | In the early stable development stage, the annual production of coal resources continued to increase. The ecosystem is in a damaged state | The original ecosystem is enhanced by external interference, and the damage to the structure and function of the ecosystem continues to accumulate, and the ecosystem becomes the damaged ecosystem |
|
Shanxi Pingshuo Antaibao open-pit coal mine | Construction began in 1982, and it was officially put into production in September 1987 | In the late stable development stage, the annual production of coal resources basically reached the highest and remained stable. The change from a damaged ecosystem to one that is degraded or severely degraded | The original ecosystem is enhanced to a certain extent by external interference and remains stable, and the damage to the structure and function of the ecosystem continues to accumulate, and the ecosystem becomes a damaged ecosystem. Mining enterprises attach importance to ecological restoration, and take reconstruction/restoration measures to the mined areas, and the damaged ecosystem gradually changes to another balanced state |
