Research On Formation Mechanism And Combination Intervence Of Coal Miners’ Unsafe Behaviors

Nowadays in China, safety in coal mine production has been improved, but it is stillsevere. According to a survey conducted over the past30years showed that above96.5%coalmine accidents are caused by human unsafe behavior. Thus, the key point to reduce majorcoal mine accidents happening is preventing and controlling human unsafe behavior. Thispaper can help us has a further clear understanding on certain law that may cause unsafebehavior occurrence and provide a theoretical basis for enhancing the level of coal minesafety. The main contents are as follows:Firstly, this paper reviewed related study and researches of unsafe behavior from thefollowing6aspects: conception, theory, formation mechanism, influencing factors,intervention countermeasures. Summarized the current lack of research with national andinternational, proposed a thesis purposes and lines of this study.Secondly, on the basis of literature review, this paper analyzed causes of miner’s unsafebehavior, giving a hypothesis from internal and external causes. Then, building a preliminaryformation mechanism model of coal miners’unsafe behavior. After tested and verified bystructural equation, this paper finally formatted the miner’s unsafe behavior mechanismmodel. Meanwhile, the author summarized three processes about how did miners’unsafebehavior happen and provided a theoretical basis for the following intervention research andportfolio construction of unsafe behavior index system.Thirdly, based on the model constructed above, this paper gave a depth analysis, fromintrinsic and extrinsic aspect, on factors which can influence coal miners’ unsafe behavior andput forward corresponding assumptions between the influencing factors. Then, building aconceptual influencing factors model of miners’ unsafe behavior. After tested and verified bystructural equation, by using Analytic Hierarchy Process, this paper draw an index system and calculated all weight, according to superiority.Finally, based on the miners’unsafe behavior mechanism model that seeks to influencingfactors for unsafe behavior, this paper proposed corresponding intervention model whichconstructed by4parts: internal causes, external causes, intervention strategies,before-now-after unsafe behavior strategies; then, analyzed the causal relationship betweenminers’unsafe behavior and intervention system, building a “before-now-after” interventionmodel; This paper constructed coal miners’unsafe behavior intervention model and“before-now-after” SD intervention model which based on system dynamics methodsrelatively and laid a foundation for simulation studies. Meanwhile, the author gave asimulation study on the models above by using Vensim PLE, analyzing the miners’unsafebehavior trend under the intervention countermeasures, comparing its influence duringprophase, metaphase and anaphase.Conceptually, this paper proposed and validated the formation mechanism ofminers’unsafe behavior and enriched the theoretical system of unsafe behavior study. Itconstructed a miners’ unsafe behavior intervention model which can reduce the frequency ofunsafe behavior occurrence and proposed corresponding combination intervention practically.Meanwhile, this study stressed the importance of behavioral control during prophase and willhelp coal mine industry improve the total miners’ unsafe behavior countermeasures system.
