Abstract: Underground injection (UI) technology provides a new direction for industrial hazardous waste disposal. By learning from foreign experience and considering the actual situation of China, the potential of applying the UI in China was analyzed, and the geological environment problems possibly caused by the UI technologies were taken full account of. On the basis of a review of foreign studies, some suggestions on carrying out UI the technologies in China were put forward, which include establishing and improving UI related laws and regulations, strengthening UI engineering environmental management capacity, and establishing and perfecting relevant licensing system.
