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...
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 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...
Most of advanced safety management systems of coal mine are about the mine production system, however as the surface production system of coal mine, the safety management of the coal washing and dressing system is still behind, most of which manage security information by handwork, but various security hidden danger are difficult to count, so management information system of coal washing and dressing...
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...
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...
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...
Coal mine water inrush is a very difficult problems which should be solved more earlier, and it have long plagued safe production of coal mines. The reliable operation of coal mine drainage systems plays a vital role in safe production of coal mines. Based on the non linear relationship of the state parameters of the coal mine drainage facilities, we propose a safety monitoring method based on BP...
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...
The system utilizes the object-oriented analysis method and the broad-based B / S / D software architecture. Then researching and developing the coal mining security equipment's intelligent monitoring and management system of being based on the web-environment, the Web server software on this system using the tomcat6.0. Connecting the database by struts and ibatis dynamic web page technology and framework...
The safety investment and benefit of coal has two characteristics: fuzziness and gray character. Considering the limited consideration of safety investment of coal, a mathematic method based on fuzzy-gray relational degree is proposed, a synthesized relational degree is formed by connecting the gray relational degree and Oushi distance of fuzzy sets. Based on the contents as concept of coal mining...
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...
The relation among job satisfaction, stress level and self-efficacy of safety staff in coalmine was investigated by a questionnaire survey conducted to 43 employees in a state-owned coalmine. The results showed as follows: stress level could predict job satisfaction negatively; self-efficacy could not only predict job satisfaction positively, but also adjust the effect of stress level on job satisfaction;...
Hidden dangers in system are the main reason that causes accident happen. Using theory of constraints, it achieved the coal mine hidden dangers divided scientifically and reasonably. On the one hand, establishing coal mine hidden danger information's constraint treating flow, it makes the definition of the coal mine worker's responsibility and ability clear. On the other hand, it study on the operating...
Through setting up models, the coal enterprises' threshold of safety input is obtained with the real option approach. Further, the results shows: the coal enterprises' safety input are influenced by following aspects critically: the efficiency of safety technologies, the quantity of the input, the raise speed and the uncertainty of the safety technical efficiency, and the policy and monitor of government.
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...
Metadata technology is significant to establish the data warehousing of coal mine safety. Effective organization and management metadata are the important issues of coal mine safety data sharing and coal mine safety data warehousing. The paper discusses the generality and difference of structure data, semi-structure and non-structure data, put forwards the three metadata structure of organization,...
Reinforcement learning is an algorithm without model which is learning what to do--how to map situations to actions-so as to maximize a numerical reward signal. Reinforcement learning provides an available method to the systems, which are very difficult to build up accurate models around complex environment. But now many practical problems demand a maximum reward with not much cost (expense). For...
Based on the ideology of "using the monitor data to reflect the production safety and using the risk analysis and safety evaluation methods to guide safety management to realize the objection of mine coal safety state warning and assistant decision-making support system", with Bofang coal mine of Shanxi Orchids Corporation's practical experience in safety state management, we set up a warning...
