• Recently, China Coal Technology Ningxia Tiandi Benniu Industrial Group Co., Ltd. released key technologies and complete sets of equipment for high mining of thin coal seams, marking a major breakthrough in intelligent mining of thin coal seams in China. Due to the high mining height and narrow space, thin coal seam mining has long faced difficulties such as high labor intensity, low automation level, and poor economic benefits. This set of equipment has successfully solved the pain points of low efficiency, poor equipment adaptability, and high manual safety risks of traditional oblique cutting. Its promotion and application will effectively release the potential of thin coal seam resource mining and promote the transformation of the coal industry towards safety, efficiency, intelligence, and green direction.Editor/Gong Ziwei
