Study on Blasting Operations Hazard Identification and Risk Assessment Based on Improved Evaluation Method LEC in Xiaocishan Mine

摘要

The study on blasting operations hazard identification and risk assessment based on improved evaluation method LEC in Xiaocishan mine was conducted to ensure the safety of blasting operations.According to the basic scoring criteria of the improved LEC method,the hazard risk assessment form was obtained.By assessing of risk size for the identified hazard during blasting operations,the risk evaluation results of hazard sources could be acquired.Then the blasting hazard assessment on the basis of improved LEC method was achieved in Xiaocishan mine,providing guidance for safety management in the subsequent blasting.
