On June 13, the world's tallest 10-meter hydraulic shield of super mining height rolled off the assembly line in Zhengzhou Coal Mining Machinery Group Co., Ltd. (ZMJ), Henan Province.

6月13日，记者从郑煤机集团获悉，世界最高10米液压支架完成首批交付。

The height of the hydraulic shield has increased from 8.8 meters before to 10 meters this time, which benefits from ZMJ’s comprehensive improvement in materials, equipment, technology, philosophy, and other aspects.

从之前8.8米的记录到这次的10米，不仅仅是支护高度上1.2米的提升，更是基础材料、加工设备、技术工艺、认知理念等全方位的提升。

The equipment will be applied to the super mining height and comprehensive working face of Shaanxi Shanmei Caojiatan Mining Co, Ltd. The working face has a length of 299.5 meters and a strike length of 6,000meters. After the equipment is put into use, the annual production of raw coal is expected to exceed 20 million tons.

该套设备将应用于陕煤曹家滩矿业超大采高工作面，工作面长299.5米，走向长度6000米，预计投入使用后，年生产原煤有望突破2000万吨。
