en.Wedoany.com Reported - The "Key Technologies and Complete Equipment for Thin Seam Equal-Height Mining" achievement release conference was recently successfully held in Shizuishan City, Ningxia Hui Autonomous Region, at China Coal Technology and Engineering Group (CCTEG) Ningxia Tiandi Benniu Industrial Group Co., Ltd. Leaders including Wang Hong, Chief Scientist of CCTEG; Ma Long, Party Leadership Group Member and Deputy Director of the Ningxia Hui Autonomous Region Department of Science and Technology; and Ma Yuqing, Deputy Mayor of Shizuishan Municipal People's Government, attended the meeting.

Yan Zhimin, Party Committee Secretary and Chairman of Tiandi Benniu, stated in his address that the newly released product represents the latest achievement leveraging the full industry chain advantages of CCTEG's "industry-academia-research-application" model. Jointly developed by Tiandi Benniu and the Taiyuan Research Institute, it aims to bridge the "last mile" of efficient thin seam mining. Targeting the mining characteristics and user needs of thin seam working faces ranging from 1.1 to 1.7 meters, the equipment innovatively establishes an equal-height mining process and equipment system. It features an equal-height shearer with a cutting power of 550 kilowatts, an integrated armored face conveyor (AFC) incorporating a conveying system, a haulage system, and a cable management system, lightweight hydraulic supports with high load-bearing capacity, and a highly integrated intelligent remote control system. The coal passage space of the equipment is increased by 80% compared to conventional products of the same specifications. The application of technologies such as vertical end cutting and automatic cable follower enables rapid face advancement, intelligent cable protection, and remote unmanned operation, improving mining efficiency by over 25%.

Attending leaders, experts, and user representatives unanimously agreed that this set of equipment successfully fills the technological gap in China's unmanned fully automated thin seam equal-height mining. It resolves the long-standing contradiction between "small space" and "high power" in thin seam mining, addressing industry pain points such as low efficiency of traditional oblique cutting, poor equipment adaptability, and high manual safety risks. User representatives from 50 major Chinese coal enterprises, including China Energy Investment Corporation, Shandong Energy Group, Shaanxi Coal and Chemical Industry Group, and Shanxi Coking Coal Group, participated in the conference.

This achievement release marks China's capability to compete at an international advanced level in the field of safe and efficient thin seam mining, providing crucial equipment support for advancing the overall progress of China's thin seam mining technology.
