Why did Jianshui Mine stop?

Did not apply for documents as required. After research by the county people's government, it was decided to close the non-coal mine enterprises such as Xinzhaitu Mine in Chenguan Town, Jianshui County 12 that failed to obtain the safety production license and mining license according to law or did not go through the formalities for extending the safety production license and mining license within the prescribed time limit.
