为研究不安全行为在煤矿工人之间的传播规律,基于社会网络视角基础,在SIR传染模型理论基础上构建煤矿工人SEIR传播模型,通过实地调研设置相关参数,并利用MATLAB对其进行仿真分析,研究煤矿工人不安全行为的传播特性。结果表明,在不安全行为传播过程中,不安全行为的传播主要集中在前期;煤矿工人间的不信任关系对不安全行为传播能力和速率有抑制作用;网络平均度<Z>过大,会导致不安全行为的传播速度加快,以及传播矿工的密度增大,最终达到稳态平衡。遗忘率η对传播矿工和免疫矿工的影响较大,与传播矿工的密度成正比关系,与免疫矿工密度成反比关系。

To study the transmission law of unsafe behavior among coal miners, based on the social network perspective and SIR contagion model theory, a coal miner SEIR transmission model is constructed. Relevant parameters are set through field research, and MATLAB is used for simulation analysis to study the transmission characteristics of unsafe behavior among coal miners. The results indicate that in the process of spreading unsafe behavior, the spread of unsafe behavior is mainly concentrated in the early stage; The lack relationship of trust among coal miners has a suppressive effect on the ability and rate of unsafe behavior transmission; If the average degree of the network <Z> is too high, it will accelerate the transmission speed of unsafe behavior and increase the density of transmission miners, ultimately reaching steady state equilibrium. The forgetting rate η has a relatively significant impact on both transmission miners and immune miners, and is directly proportional to the density of transmission miners and inversely proportional to the density of immune miners.
