850 days of continuous work|Sany helped Yongming Coal Mine build a normalized unmanned intelligent coal mining face

Recently, Sany Heavy Equipment and Shaanxi Yongming Coal Mine successfully built an unmanned intelligent working face for normal ground remote mining that works continuously for 850 days - no one enters the working face during production, achieving the safety goal of being safe without man.

The 1515 working face of Yongming Coal Mine integrates intelligent control and integration linkage, and automatically follows the machine through hydraulic supports.ShearersThe control method of combining memory cutting and ground remote intervention uses key technologies such as video inspection of the whole working face, linkage between hydraulic support and transportation equipment, and equipment fault diagnosis to realize the automatic operation of the working face shearer, hydraulic support and transportation equipment during the production operation, and no one interferes in the continuous operation in the working face.

As of a few days ago, the working face has produced a total of 2,125 knives, advanced 1,700 meters, and produced 728,500 tons of raw coal. At present, the production class of the working face adopts normal production on the ground, with a production efficiency increase of 71.4%, and has been successfully shortlisted for the finals of the thin coal seam track of the 2023 National Coal Mining Face Intelligent Innovation Competition.

Since the completion of the unmanned intelligent coal mining face of Yongming Coal Mine, it has been unanimously recognized by many leaders and experts such as Shanneng Group and the Tongchuan Bureau of the State Mine Safety Supervision Bureau. In the process of development of the coal industry, Sany Heavy Equipment has always adhered to the corporate mission of "quality changes the world", and continued to promote the intelligent upgrading and high-quality development of the industry in the spirit of responsibility, pragmatism, innovation and lean.
