Energy development and utilization play an important role in Henan's economic growth. During more than past 20 year, energy use efficiency has been improved greatly, but there is still a large potential for energy and emission reduction. Firstly, using the method of Grey relevancy analysis to get the model between energy consumption and economic growth in Henan before and after 1990.Secondly, we analysis...
Based on the endogenous economic growth model, this paper presented a growth model with the consumption proportion of exhaustible resources and pollution control and then obtained the optimal economic growth path solutions. The prerequisites to optimal growth path are discussed based on these solutions. At last, some suggestions were given under the comparative static analysis of variables.
Because of the developing environment, the occurring conditions and the randomness, uncertainty and fuzziness of mine water inrush, it is a very complex nonlinear system to determination of mine water inrush sources. Artificial neural network is of the stronger self-organization, self-adaptability and self-learning capability, which is specially suited to solve nonlinear problems. In the paper, we...
Because the present safety evaluation could not exactly make the quantitative conclusions, this paper analyzes the reasons why the present evaluation methods are difficult to make the quantitative conclusions and provides the probability estimation method of the gas and coal dust explosion risk. Using this method determines the gas and coal dust explosion risk and gets the quantitative results of...
The accurate test of coal seam outburst indexes is the foundation of coal and gas outburst forecast. Recurring to well-rounded uncertainty theory and technology can build the optimization method of outburst forecast indexes aiming at the testing process complexity. Firstly, uncertain factors of effecting test results were analyzed, an uncertainty mathematics model was established based on Taylor series,...
In order to solve the problems encountered in transformation process of Pingxiang, this paper makes a comparative analysis on the transformation experience of typical resource-dependent cities both domestic and abroad, at the same time, the work experience of Pingxiang's transformation is discussed. Three main aspects are mentioned in this paper: firstly, the paper gives detail information about the...
Energy crisis today contains not only the phenomenal of energy storage, but also unbalanced structure of energy production and consumption. With the fast development of economy, China's demand for energy is more and larger than the past. In this paper, Heilongjiang province as an important energy base is studied. Heilongjiang' existing energy problems are proposed and corresponding strategies are...
Diversification is a mode of operation which is widely used by the development of group companies. The reason is that diversification can play internal strength, access to synergistic effect of resources, and enable enterprises to the orbit of strengthen and expand. But in reality, many businesses will also diversified into the development of difficulty or even go bankrupt. In order to stay sustainable...
Various subsidiaries of coal enterprises have enormous development potential in coal product provision, but how to make the large logistics of subsidiaries be reasonably resolved, as well as offer a new profits and increase benefits for enterprises, is a real problem needed to be solved. This article analyzes the logistics management system of coal enterprises, and puts forward some suggestions for...
Based on Circular Economy and the evaluation index system of general principles, combined with the characteristics of China's coal companies, Coal enterprises built this first evaluation index system of circular economy. The index system consists of resource outputs, resource consumption, comprehensive utilization of resources, waste disposal four-level indicators, each level indicators and include...
This paper use the gray single-level evaluation evaluate coal enterprises' security condition with a gray theory, let the coal enterprise's evaluation be more scientific and more realistic and provide a reference for the safe appraisal of coal enterprise.
In order to solve the coal roof stress analysis and prediction with multiple data information, an expert system is used in this paper. By introducing coal roof stress information forecasting model and expert system model, the MIS can rationally make individual data analysis to multiple data comprehensive analysis, and the coal roof management information system is designed. Experimental analysis shows...
Considering the environmental benefit of eliminating the pollution of coal enterprises has regional cumulative effects, we use the principle of large-scale system to establish regional coal companies economic coordination control model, and make an empirical study as the coal industry in Henan Province. The conclusion is that the environmental economic development level of the coal industry in Henan...
In order to fully evaluate and understand the environmental pollution situation, and find out the distribution of regional environmental pollution and the gap, we use the Theil coefficient to analyze the regional sulfur dioxide emissions in Henan Province, which will provide a theoretical decision-making for government to further deploy environmental pollution control measures and develop differentiated...
Industrial technology policy, including industrial research, development and aid policies, etc., is an important method to make sure industrial technology to be properly and effectively developed. This paper says, in recent years, Henan government promulgated and implemented a series of industrial technology policies to encourage and support technology innovation, such as “Developing Henan with Science...
The coal industry as the basis for the national economy sectors, the financing of its debt maturity structure of listed companies on the development of China's coal is significant. In this paper, our object of study of coal listed companies, the use of multiple regression analysis,to research the coal company's debt maturity structure listed the factors affecting, obtained through empirical testing...
The development of Chinese coal enterprises has been restricted by the absence of drive on institution and a general strategic planning and the lack of features and innovations in form when developing circular economy. In this paper, the idea of flexibly developing circular economy has been put forward in order to adapt to the complicated and volatile maket. First of all, the flexibly developing capacity...
The exploitation of coal seam gas is influenced by various geological factors. In order to study the weights of these factors, this paper establishes a BP neural network prediction model by taking No.3 coal seam in the representative area of southern Qinshui basin as an example. It finds out that the potential coal-seam gas capacity of southern area of Qinshui basin is influenced by some primary factors...
There is no unified principle for the description and storage of metadata in the current information system which the coal mine enterprise exists in, neither does it benefit the management and maintenance of system, nor the integration with other system. According to the standards of relevant metadata and the characteristic of coal and gas outburst factors data, this paper proposed the data storage...
In knowledge economy era, loyalty of knowledge-type staff determines modern enterprise's fate, how to manage the loyalty of knowledge-type staff has become an important task of nationalized coal enterprise. First, loyalty fall to knowledge-type staff in nationalized coal enterprise is introduced. Then, material reasons of loyalty fall are analyzed in detail. Finally, some strategies are put forward...
