There is an age limit for centralized belt controllers in coal mines. Age limit for recruitment of coal mine centralized controllers: at least 16 years old, with no more than 60 males and no more than 50 females. According to the provisions of the Labor Contract Law, people who have reached the age of 16, men who have not exceeded 60, and women who have not exceeded 50 (no more than 55 management positions) are protected by the Labor Contract Law. China's "Labor Law", "Labor Contract Law" and "Law on the Protection of Minors" all clearly stipulate that employers are prohibited from recruiting minors under the age of 16. Therefore, the minimum age of the object protected by the labor law is 16 years old.
