The extension method based on entropy weight is a new safety evaluation method. Entropy weight, which is an objective weight, was ascertained by entropy theory. As a result, the subjectivity in ascertaining the weights of more factors in lower hierarchy was avoided. The comprehensive correlative degree was taken as the evaluation criteria in this method. Therefore the subjectivity of evaluation model...
Human errors which have been affecting safety accidents are one of the main reasons in coal mine. So these Accidents can be pre vented and reduced through analyzing human errors affecting factors. This paper has made elaborate analysis of the relative affecting factors which cause human errors through applying the Gray Relational Theory in coal mine accidents. Based upon this specific analysis, by...
In this paper, we propose a new multi-expert decision-making method based on induced OWA operators for coal mine safety evaluation. Aggregation operators are crucial to decision-makers when they make decisions. The Ordered Weighted Aggregation (OWA) is the most common operator to aggregate the arguments that are the exact numerical values. However, the decision-makers may have vague knowledge about...
Human, machines and environment, three main factors contained in transport system in coal mines, and their impact on transport accident have been analyzed with system engineering theory of man-machine-environment in this article. Reasons and control of human mistakes, relationship between human and transport accident, analysis of machines' stability and fuzzy comprehensive evaluation have been deeply...
Coal mines safety condition decides the economic condition of the regional development on one hand, more importantly the safety of employees working for mines on the other. This article has introduced a scientific system to evaluate the safety level of coal mine based on AHP so as to give out significant information for the managers of coal mine to make and implement corresponding polices concerning...
The occurrence of accident be understood as mutations in a qualitative change caused by a continuous change of some of the parameters within the system. The system from security state into the state is actually a mutation phenomenon. The paper applies the Catastrophe theory and system analysis method of the accident causation, establishes the spire catastrophe model. By analysing the model, indicates...
Most of the coalmine accidents are caused by people's unsafe behavior. Based on the basic theory and research methods of behavioral science, this paper analyzed human factors and rules affecting unsafe behavior. On this basis, it proposed the wholly integrated coalmine safety culture construction methods, with strengthening safety awareness, correcting unsafe behavior and training security practices...
Owing to the complexity of human behaviors in risk situation and the harsh physical environment of underground mine, current researches on coalmine virtual environment have paid little attention on modeling human risk behaviors. Based on Artificial Life method, an intelligent virtual miner agent model was proposed to yield better understandings of human factors in emergency situation and to assist...
The coal enterprise behavior safety integrated management and control system is the integrated management and control information system which takes the behavior safety as the core and aims to guide safe behavior and realize coal safety supervision. In this article, we describe the theoretical base of the system design, i.e. the theoretical frame of the accident prevention and control for coal enterprises...
Coal mine safety evaluation analyses mine's existent dangerous and harmful factors, and judges mine's potential risks. The evaluation result is propitious to guard against accidents and make management decisions. This paper analyses all kinds of influence elements on coal mine safety, constructs evaluation indexes system, measures weights using AHP, and applies dynamic fuzzy theory in mine safety...
Safety is one of the key problems people concern about most not only at present but also in the future. Currently there are many hidden troubles threatening safety. Particularly, the safety problems in coal mines are very serious and in great need of management and control, because they not only influence humanpsilas increasing demand for energy, but also affect severely environment. Hence, itpsilas...
