China Coal Zhang Jiakou Coal Mining Machinery Company (ZMM), situated in Zhang Jiakou, a mountain city on the northern frontier of the Great Wall. It lies to the east of Beijing, capital of China, and join west of two immense coal mine resource in Shanxi, and inner Mongolia. The location cross border between Beijing-Tianjin-Hebei economic zone and Jin-Ji-Mon area make it have geographical advantage. In 1926, The factory was built originally as a coin mint owned by General Feng Yuxiang and then became a munitions factory of General Fu Zuoyi..After 1949, it was transformed into a professional coal mining machinery factory, which was one of three earliest coal mining equipment suppliers. In 2014, the factory was developed to a subsidiary corporation under the China Coal Mining Machinery Equipment Co., Ltd exclusively-invested by China Coal Group Corporation.

The machines produced by ZMM are serious of AFC conveyor, Stage loader, crusher, plough, which are popular either in the transportation system or cutting system during the coal mining process. And also includes complete set of unmanned automatic conveyor,  complete set of fully-automatic plough system on thin seam workface. The equipments are classified into 10 group, 82 serious, 500 dimensions of products with the working power coverage from 40 kilowatts to 4800 kilowatts, transmission capability ranged from 150ts/hr to 6000ts/hr. The maximum designed work length has reached 400 meters. With technology innovative capability, ZMM developed diversity of mining devices including flame-proof eletric-switcher, Solid-liquid separate pressure filter, engineering hydraulic cylinders. With producing capability, It provides not only sorts of construction chains for ore mining, metallurgical plant, engineering works but also top-quality chain connector of which technology transferred from Parsons and produced by Sino-Polish Joint Venture which invested by Gwarant (originally FKI company) and ZMM. With developing capability in producing high tension mining chains and industrial chains, ZMM is granted as the abound mining chain supplying resource and head manufacturer..
