Why is Guangdong Coal Mine closed?

Guangdong coal mine closed because of incomplete licenses and backward technology. The coal mines in Guangdong are small in scale and low in quality. The annual output of coal in the province is only over 8 million tons, accounting for a small proportion in the province's economy. Most coal mines have incomplete licenses, backward mining technology, poor safety production conditions and serious damage to environmental resources. On the one hand, the gradual closure of coal mines is to ensure the safety of people's lives and property. Therefore, Guangdong coal mine closed because of incomplete licenses and backward technology.
