Depletion in Malaysia's fossil fuels has caused the country to explore other potential energy source. Of all possible options, nuclear power has been considered the best. However, the plan for its implementation has been met with many challenges primarily within the issue of acceptance among public. This paper explores challenges of implementing nuclear power in Malaysia. Data were obtained through...
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...
Eco-friendly yards, in which coal is stored in closed silos, can reduce the dust pollution in coal ports. However, the daily operation of coal ports with eco-friendly yards involves complex management strategies such as train collection strategies, storage strategies and so on, which should be studied to enhance the efficiency and cut down the cost. Thus, this paper aims to optimize the key train...
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...
In order to reduce the costs and maximize the profit, many coal mining enterprises are gaming in the safety investment under the coal-mining supervision in China although relative supervision provisions are strict, which results in mine accidents happening. In order to make sense the causes that are behind the economic motivation, based on the gaming model with two variables, technology and cost,...
In this paper the necessity to apply Internet of Things (Hereinafter referred to as IOT) in the coal industry is analyzed. The architecture of a new kind of IOT for coal mine and its main technical indicators are proposed based on sensor technology, combined with Industrial Ethernet, 3G/WIFI wireless networks, wireless sensor networks and other technologies.
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,...
In allusion to the failure data submergence in a circuit breaker burning accident in a conventional substation of a coal mine, and in view of those supervision and control system defects in a conventional substation such as information islands, complication of network nodes and subsystems, nonstandardization of application function, poor expansion of system, and also high charge of operating and maintenance,...
In order to improve the safety of coal mine production further, the paper designs a roof abscission layer wireless monitoring system based on 433MHz RF technology. Monitoring sub-stations and nodes under the ground form a distributed wireless network and communicate with each other via wireless data transmission module CC1100. In this wireless network, sub-stations, connecting to remote monitoring...
Coal detection is mainly carried out in accordance with the relevant standards and regulations for coal tests and analysis. Coal detection needs to have support of certain technology. Detection management system is a set of work procedures that is specially designed for coal testing. Through the strict management of coal inspection management system for coal detection, in which computer technology...
A multi-period mixed integer programming model is presented in this paper to reduce the overall cost of coal purchasing and transport in large-scale power generation group with the consideration of the stochastic coal demand. Mixed integer liner programming is used in problem formulation considering inherent connection between purchasing and inventory routing, and scenario tree method is applied to...
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.
Coal mine safety funds are divided into employee's safety input funds, safety technology funds, and safety management funds. It is great significance for the realization of the optimal safety input orientation and the selection of safety projects to scientifically allot each safety funds. This paper uses co integration test and Granger causality test to explore the long-term steady relationship between...
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...
Coal mining is restricted by various mine geological disaster, and the largest mine safety issues are the water-inrush accidents. The precondition of Coal mine safety and production is ensuring the safety of coal floor. Usually coal floor is composed by different rock, it cannot be directly applied for mechanics model to analyze and calculate. In this article different formation stratum are reduced...
For the shortcomings of the traditional performance diagnosis method of power plant boiler current, the paper proposed a method of introducing the fuzzy comprehensive evaluation into performance diagnosis of power plant boiler. This method first took the boiler safety, economy and environmental protection three aspects into account to find boiler performance parameters. In order to accurately understand...
Based on the long-term field observation, it is to analyze the coal wall collapsing and saplling mechanics of the high cutting coal mining face, and put forth that existence of the weaken spot or face on the coal wall is the basic reason which cause the coal wall collapsing and saplling of the high cutting coal mining face. According to the coal wall collapsing and saplling characteristic, establishing...
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...
This study will analyze the refined safety management of Chinese coal enterprise by means of the high-level interviews, case analysis and investigation. And it will also use real evidence and case studies to verify the effectiveness of contents and systems of the enterprises' refined safety management. This work will help the enterprises shake off backwardness and low efficiency of safety management...
