Coalbed methane is not only a valuable clean resource, but also a major hazard in coal mine safety production. The discerption of mining right leads to the contradiction between the coal enterprise and the coalbed methane enterprise, which hinders the healthy development of coal and coalbed methane industry. Based on Game Theory, this paper studies the coalbed methane cooperative mining under the...
Production safety is concerned continuously in coalmine, especially the gas safety is a key issue in the working management of coal production. With the development of information technology, a large volume of data should collected from sensors deployed in coalmine. Therefore, it is necessary to forecast gas concentration or evaluate the gas safety in the key point, for example, the underground working...
Bangladesh is said to be one of the biggest energy starved countries, with the present demand for electricity at 9000 plus MW (Mega Watt) as opposed to the production of 6500 to 7500 MW. Access to electricity in Bangladesh is one of the lowest, about 40 percent of the total population are without access to adequate, cheap and quality energy. At present, we have to depend on indigenous energy resources,...
Curvature reflects the size of bending degree of curve. In this paper, we put forward a new relational degree model based on curvature of the two series. The new model satisfies the parallel property and uniform property. It is consistent with the actual situation by comparison to the existing relational models. At the end, we give a case in order to validate the new model.
This paper aims at applying ART-2 neural network algorithm on the research of coal mine safety risk assessment and finally obtains good empirical results by taking some coal mines as the study sample. The results show that the ART-2 neural network algorithm is an appropriate method to assess the safety risk of coal mine. The analysis of empirical results is consistent with the actual situation.
As we all know, coal is an important basic resource which accounts for about 70% in the primary energy structure. Coal mining enterprises have the primary responsibility of the mine accident. Therefore, it is a great significance with researching the production strategy of coal mining enterprises. In this paper, we use the game theory to analyze the interest between safe-production of the coal mining...
The purpose of this paper is to solve the difficult problem that coal mine accident cannot be effectively contained by the government's severe consolidation, and to deal with the main stakeholders' conflict of interest and information asymmetry in coal mine safety regulation. Systematically, we analyzed the three-tier principal-agent relationships which formed in the coal mine safety supervision and...
As for coal enterprise, whether it should maximize profit, or maximize sales for the target that more beneficial to development of coal enterprise and coal industry, which is always a study problem in economy circles. Economics theory is applied in this thesis, infer that coal enterprise' target profit of seeking sales maximization is lower than maximal possibility profit, and more Safety -Energy...
In recent years, along with the aggravating social competition, the coal enterprises take security cost control more seriously, but when those coal enterprises carried on the management, they often neglect many recessive security cost. However, only by recognizing and taking these recessive security cost under control, can we improve the cost conditions of coal enterprise fundamentally, promote its...
This paper investigates the security role of “three laws and one regulation” on coal mine safety production in China through a dummy variable model analysis. The results show that the security role of “three laws and one regulation” made the death rate reduced by 0.895 persons per million tons coal. The terms of economic penalties and sanctions would be closely consistent with the level of economic...
The rapid development of China coal mine safety management information play an important role on improving mine safety standards, however, there exist some problems such as cannot be a comprehensive system of monitoring, evaluation and analysis of safety, forecasting of security trends, etc. Papers have researched based on this problem, carrying out research on an analysis and collection of security...
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...
Aiming at the drawbacks in disposing coalmine accident hidden troubles the paper sets forth the market-oriented concept and method of coalmine accident hidden troubles. The method fixes on the quantitative value of unsafety state and the hidden troubles factors composed with behavior, technology, environment, and equipment, and establishes accident hidden troubles price system. It constructs the market-oriented...
The sense of mining progress was analyzed. The model of production function considering mining technical progress and mining condition of coal bed was proposed. The growth equation and the production function were deduced when the two factors were considered. The research indicates that mining technical progress has a great effect on the output of mine enterprise when mining technology develops promptly...
In view of the severe situation in coal mine safety production, using tomcat6.0 as the Web server software, through the dynamic web page struts technology and ibatis framework technology to realize database connectivity, using Myeclipse 5.5.1 as a development tool, we develope the web-based system which is monitoring and managing of the coal mine safety equipment intelligently. For different units,...
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...
In order to reveal major factors constraining China's coalmine safety, the principal-agent relationship in China coalmine safety management is analyzed, a multi-task incentive model is constructed by setting different functions of production and safety performance, the coalmine manager's work behavior under optimal incentive contracts is analyzed and some meaningful conclusions are obtained. It is...
Aim at the unsafe manager behavior underground the China coalmine accidents taking place frequently recently, the two-layer principal-agent relationship in China coalmine management is analyzed, the double level multi-task incentive model consisting of government, company and coalmine manager is constructed, the coalmine manager's work behavior under optimal incentive contracts is analyzed and some...
The coal safety regulations play an important role during Chinese coal production, which greatly effects the progress of Chinese mining technology. Furthermore, in the market-oriented condition, safety input is an important factor that increases the production cost of the mine companies. By constructing profit-maximizing model, the article discusses how do the safety regulations impact Chinese coal...
