What Is Waste Coal?

Due to artificial mining factors, the former mining area with rich coal resources has become a depleted coal mining area. The area abandoned by humans due to the interests and other environmental protection factors is not enough to continue mining and utilization, which is called waste coal mine. The existed history of waste coal mines in China is relatively long and the distribution range is wide. The scale of waste coal mines is also different. A large number of waste coal mines have appeared in Datong and Ordos in resource-exhausted cities.

The main reason for the emergence of waste mines is the excessive exploitation of coal resources, which has caused the coal resources in the mining area to drop to a very low level. The cost of mining surplus coal by coal companies is much higher than the value of coal, so many coal companies will stop Due to the mining of coal resources in the mining area, there are waste mines that no one uses. Coupled with the country's increased efforts to protect the environment, many new coal mines that have just been mined have a large number of environmental pollution problems due to the backwardness of their coal mining equipment, forcing many companies to give up further coal mining. This is also the result of waste coal mines. One reason. In addition, driven by interest, the phenomenon of private mining of coal mines prevails, leaving many abandoned coal mines that have not been counted. ^[1]

See how the Laoshan Coal Mine "picked out" 2.4 billion yuan from abandoned mines: Open the report materials of the Shanxi Lanhua Group Laoshan Coal Mine Co., Ltd. to the Land and Resources Department, and the column of resource reserves. From 2003 to 2015, it was always filled in "Exhausted resources."

However, since 2003, the mine has been continuously mining more than 300,000 tons of resources from the ground each year, achieving economic benefits of 2.4 billion yuan, not only extending the service life of the mine, but also effectively improving the recovery rate of coal resources. A new way to rely on scientific and technological innovation to comprehensively promote resource conservation. ^[2]

Abandoned coal mines in the United States rejuvenate through the tourism industry: The coal mine built the company city, and Jack and Sandra Looney hope that the vineyards on the mine will attract tourists. They built the Highland Winery on top of the "Company Store", telling the history of the coal mine area, which also created three iconic wines for them: Blood, Sweat, Tears (blood, sweat, tears) . ^[3]
