Abstract: A variety of environmental geology problems were induced by mining, and serious problems of environmental geology in some mines have constrained social and economic sustainable development in these areas. In order to understanding the current status of mine environmental geology problems, China Geological Survey has successively laid out mine geology environment investigation and research work of different scales for the northwest region of China, five provinces (autonomous regions) and key ore districts since 2001. A large number of foundational and comprehensive maps have been compiled. This paper preliminarily summarizes the compilation type, content, expression ways and characteristics of maps of mine geological environment investigation and research at different scales in the northwest region of China which have been completed now. This study aims to promote and upgrade the technology of mine environment map compilation and provide scientific information for mine geological environmental protection and control.
