OREANDA-NEWS. January 21, 2015. The Packaged Technology and Equipment Project of the Fully Mechanized Top-coal Caving with Large Mining Height in the Extra-thick Coal Seam, jointly developed by Datong Coal Mine Group, China Coal Technology Engineering Group, Shanxi Pingyang Machinery and Equipment Company, and a number of research institutes and manufacturers, won the first prize of national science and technology progress award.

Got successful popularization and application, this project effectively solves the high yield, high efficiency, high recovery rate, safe mining and other technical problems in special thick coal seam, and fills in the blank of the technology of national thick coal seam mining, which makes the national comprehensive mechanized caving mining technology realize a qualitative leap in the revitalization of the equipment manufacturing industry and plays a positive role in promoting coal industry health and sustainable development.
