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...
Safety warning management is a new method of safety management in coal mine, which helps to ease the prevention shortage and change passive situation facing safety accident. The object on early warning management is greatly important for warning management, which affecting warning results seriously. This paper has constructed safety warning management factors system based on literature summary, expert...
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,...
Well-balanced and suitable ventilation is the postulate to keep the health of underground worker and the safety of the production. We take air quantity of laneway as the research emphasis, considering the release of state regulations on coal mine, we figure out the optimum area of air quantity via building the optimization programming model, and realize an actual case study to interpret the process...
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 upgrading of China's coal mine detection equipment and technical means are very backward, mainly distributed instruments and devices, low efficiency, poor accuracy, detection and testing of the limitations of the data, testing methods, data-processing technology is backward. Unable to provide an objective and impartial technical data to meet modern coal mine production safety needs. In this paper,...
Based on introduction of the background and the limitations of present methods for coal and gas outburst, a hybrid method for prediction of coal and gas outburst based on soft sensor and data fusion combining many associated dynamic and static influence factors is proposed. In the method, the data fusion method based on arithmetic mean and batch estimation is used to process the dynamic influence...
Structural equation model is constructed to discuss the interaction between affecting factors of safety management capability of coal mine. Fundamental data is acquired from questionnaire of coal mine worker. 20 factors in all classified into four layers: worker, team, firm and environment are extracted in questionnaire. Taking factors of worker layer as endogenous latent variable, taking factors...
