摘要
In order to reduce casualties and accident losses caused by blasting safety accidents in open? pit mines, SNA was used to construct the relationship network model of blasting safety risk factors in open? pit mines (A model network) and the relationship network model between safety risk factors and safety accidents (B model network). The relationship between risk factors and blasting accidents and risk factors was studied, and the risk assessment model of open?pit blasting safety based on SNA was proposed. It is determined that the core risk factors affecting the blasting safety of open?pit mines were inadequate guidance and inspection of blasting technology, weak safety awareness and illegal operation. And the key relationship of key control is from bad weather to illegal operation. After risk control, the overall network density and intermediate center potential of the network decreased by 75% and 100%, respectively. Researches has shown that risk can be effectively controlled through targeted intervention of core risk factors and cutting off key relationships. ? 2022 China Safety Science Journal.
