| Abstract: | The methods and content of safety assessment of controlled blasting engineering in city are systematical discussed based on Preliminary Hazard Analysis(PHA),establishing a list of hazard assessment of the operation unit of controlled blasting in city.Risks and hazard factors of blasting system can be distinguished and analyzed by the safety assessment so as to determine the possibility of accident occurrence and its severe degree in the blasting system,and hence offering a scientific foundation of preparing protective measures and management policies.Besides,it is of a reference meaning both for reducing dangers resulting from blasting accidents and for ensuring the controlled blasting in city to be operated safely. |
