Abstract: In order to effectively control the illegal dust masks wearing of coal miners and identify the influencing factors for the spread and intervention of illegal behavior,a behavior dissemination model for coal miners wearing dust masks in violation of regulations was constructed based on a small world network. It′s showed that a behavior propagation model based on small world networks can simulate the propagation process of complex violations of dust masks worn by coal miners,and visually analyze and predict it. The spread of illegal dust masks wearing of coal miners accelerates with the increase of coal mine scale,but the growth rate tends to slow down when the coal mine scale exceeds 300 people. When the effective rate of pre-intervention reaches 40%,or the effective rate of post-intervention reaches over 50%,it can prevent the widespread spread of illegal wearing of dust masks. When the effective rate of pre-intervention reaches over 70%,it can effectively prevent the spread of illegal wearing behavior among workers. Even if the effective rate of post-intervention reaches 100%,the number of workers who violate regulations can still reach 18. 0% ~ 22. 7% of the total number of workers after the spread of violations. The effective rate of pre-intervention reaches 20% ~ 30%,with different degrees of post-intervention,the effect is better than simply using pre or post intervention.
