About Zhengzhou Coal Mining Machinery
Zhengzhou Coal Mining Machinery Group Co., Ltd. (ZMJ) is a Chinese mining machinery manufacturer founded in 1958 and headquartered in Zhengzhou, Henan, listed in Shanghai and Hong Kong. It is regarded as the world's largest supplier of fully mechanised coal mining technology and equipment, and is the birthplace of China's first hydraulic roof support, the centrepiece of its specialisation.
Its core business is complete longwall face equipment: hydraulic supports of record height and working resistance, shearers, armoured face conveyors, electro-hydraulic and intelligent face control systems, and smart mine solutions with full life-cycle service. The group also runs a significant automotive components business through subsidiaries, separate from the mining activity that defines this listing.
From Zhengzhou, ZMJ supplies equipment to China's major coal groups and exports complete systems to countries including Russia, the United States, Australia, Turkey, India and Vietnam. Its annual capacity for hydraulic supports and its record-setting support heights and working resistances make it a global reference in mechanised underground coal mining.
