Based on the development trend of the survey and design industry, this article analyzes the problems existing in the promotion of BIM technology in coal design enterprises, and proposes a construction route for enterprise level BIM technology application system from the aspects of organizational structure setting, technical team construction, software and hardware configuration, project implementation and application, enterprise family library and model library, standards and guidelines, and guarantee measures, with technical team construction as the foundation and focus, and project implementation as the starting point. Through 4 years of construction, the comprehensive popularization of BIM technology among young and middle-aged design employees has been basically achieved. BIM technology has been deeply applied in the design and engineering general contracting of feasibility studies in mines, underground cooling system and coal storage and blending bases, accumulating a professional library and organizing design process and experience into enterprise standards and guidelines, provides a platform for promoting BIM technology within the enterprise.
