Based on practice about the safety evaluation technology which was used in disposing the hidden trouble of the large complicated mined-out stope in some mine, the paper contains mainly the summary and analysises on the technology which can be used to deal with the hidden-trouble in the same situation. In order to obtain the scientific, objective and fair evaluation findings, the technology should be based on in-depth fieldwork investigation combined with effective safety assessment methods. The paper provides a useful reference for the safety evaluation of the same project.
