A dead-circle of coal-mine disaster has formed in the long-term games among local government, coal miners and coal-mine managers under the special ecological circumstances of Chinese coal-mine. The mechanism of it is discussed by game theory based on enterprise ecology in this study. It concludes that the collusion between the local government and coal-mine manager will be more rampant along with...
Accident is originated by hidden danger. Discovering and removing hidden dangers is one main approach to prevent and control accidents. This paper collected and analyzed the information of hidden dangers from multiple coal mines. On that basis, we put forward concepts of hidden danger information and standard database of hidden danger information, introduced the structure and build flow chart of standard...
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...
In the process of coal mine construction, it is significant that how to identify the risk factors and to take measures to prevent the occurrence of safety accidents for the mine investment unit to speed up the construction of the new mines and exploit the coal energy rationally. With the ability of structural equation model that processes the variables and their relationship, this article applied...
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...
If the complicated system wants to be good running, it should have a stable initial condition. The function of checking hidden danger information system of the coal mine's production in the accident control becomes more and more important. Taking tunneling waking face, we established the checking hidden danger information flow by stages, based on systems' characteristics: Initial condition dependence,...
A novel alarming assessment model of coalmine gas is presented in this paper. Based on the information fusion technique of multi-sensor, we introduce the thought of variable fuzzy set to assess complicated and risk coalmine gas. Through information fusion we can get more effective and reliable data about coalmine gas. The method for variable fuzzy set theory can reasonable identify the relative membership...
China is a country with high coal production and consumption. Being the main energy resource of China, coal has provided a reliable energy supply for the sustainable development of the countries national economy. Coal in China has made a great contribution for the national economic development, but it has also caused a negative influence on the ecological environment in China. This paper introduces...
The coalmine gas hazard affected safety of China coalmine production most. As there were lots of complicated and uncertain factors during gas accidents emergency rescue and making decisions process, accurate decisions can not be drawn by mathematics models with present information monitored by the KJ series monitoring systems such as KJ90, so experiences of former questions were urgently required...
