不安全操作对煤矿生产系统因果回路及安全影响

Effect of Unsafe Operation on Causal Loop and Safety of Coal Mine Production System

矿井事故频发引起很多专家的注意,不安全操作对煤矿生产系统的安全影响很大。根据动力学控制原理,利用VensimPLE系统构建仿真模型,探讨了不安全行为引起的煤矿生产效率和安全性变化。研究结果表明,初期自我控制能力干预时,形成了稳定安全价值观水平,但最初阶段安全态度就呈现持续下降特点,说明矿工个人价值观虽然保持相对稳定,但外部因素作用会引起个人对工作与具体行为出现明显变化。处于初始状态下,煤矿效率和安全性的相互关系与该情境下的自制力初值提高10%,煤矿的安全性变化规律明显。对各类情况调整不安全行为指标后,各系统都达到了更高的安全性。抑制冒险行为可以对安全性起到最明显抑制效果,增强矿工安全价值观也能够有效促进煤矿的安全性提升。

Frequent mine accidents have attracted the attention of many experts.Unsafe operation has a great impact on the safety of coal mine production system.According to the dynamic control principle,VensimPLE system is used to build a simulation model to discuss the changes of coal mine production efficiency and safety caused by unsafe behavior.The results show that when the self-control ability is intervened in the early stage,the level of stable safety values is formed,but the safety attitude at the initial stage shows a continuous decline,indicating that although the personal values of miners remain relatively stable,the external factors will cause significant changes in personal work and specific behavior.In the initial state,the mutual relationship between coal mine efficiency and safety,and the initial value of self-control in the situation increased by 10%,and the change law of coal mine safety is obvious.After adjusting the unsafe behavior index for all kinds of situations,all systems achieve higher safety.The inhibition of risk-taking behavior can have the most obvious inhibition effect on safety,and enhancing the safety values of miners can also effectively promote the safety of coal mines.
