Abstract:Underground pouring technology has opened up a new path for the discharge of industrial waste water in China, which greatly relieved the pressure of the surface environment. In order to ensure the safety and effectiveness of the underground perfusion, the underground perfusion technique requires a high requirement for geological conditions. In this paper, the regional geological conditions have been analyzed, the conceptual model of underground storage space has been established, and the storage space has been determined established. The effects of regional geological environment have been analyzed as well. It will provide scientific references for underground storage in northwest area of Shandong province
