    Connotation, research status, and development directions of clean coal geology in China by Yuegang TANG, Shaoqing WANG, Xiaoshuai WANG, Xin GUO, Yafeng WANG, Liping XUE, Harold H. Schobert

    Published 2025-01-01
    “…[Issues and Prospects] This study proposes some scientific and technical problems concerning coal formation, organic/inorganic elements, minerals, and clean assessment, positing that future advancements in chemistry, physics, biology, and big data/artificial intelligence (AI) will bring opportunities for the further development of clean coal geology and its applications in large-scale engineering. In the next decade, important research and development directions will include the spatiotemporal distribution of clean coals; the green, intelligent, quality-based combined production of paragenetic and associated minerals like coal gas; clean coal gasification; coal-based novel materials; underground coal-to-chemicals, and ecological restoration. …”
