Study On Integrated Technology Based On Roof Dynamic Monitoring

The research on the subject is an integral part of "dynamic monitoring of coal mine roof system", it is a science and technology tackle key projects in Shandong Province (item number: 2008GGA09001), is the implementation of China's coal mine safety production "Eleventh Five-Year" plan and mine safety technology " Eleventh Five-Year "concrete action plan for the development of China's coal mine safety, it is of great important practical significance and long-term strategic significance to build a harmonious society.(1) According to the different, including types and source of underground pressure information, monitoring location, it is divided the underground pressure information monitoring range into three areas: coal face observation area (I), internal stress observation zone (II), external stress observation zone (III). According to sources of information to partition, it is easier to reveal the regularity of mine pressure behavior. Underground pressure information integration is the focus of the study characterized the process of advancing superincumbent stratum pressure and the regularity of movement. Mine pressure behavior, "the three elements of features (including mine pressure behavior of the time, location and extent) differences is the key of information integration. By source of pressure information dividing different district, it can reveals the basic regular of pressure behavior, it is the basic law of information integration.(2) Applying the object-oriented technology analyze the needs of dynamic monitoring of coal mine roof system. System integration includes data integration, information integration, hardware and network integration, software and analysis and integrating prediction algorithm. Using UML to the entire system analysis and modeling, it improves the speed and efficiency of Software development.(3) The application of integrated systems of C / S + B / S of the network topology enhance the speed communication of mine networks, as well as improve the entire control network communications reliability especially control layer. Paper details the design principles, methods and steps and giving the system communication protocol of coal mine roof dynamic monitoring system. It focuses on the principles of database design and structure, the network database access using ADO.NET to access the technology, and design of the GPRS system and network information security issues are discussed.(4) The roof integrated dynamic monitoring information include mine-dimensional real-time information, through pattern recognition and the establishment of the normalized non-dimensional information, and can at the same time and space in a comparative analysis of the relationship between the integrated decision-making information. Normal use of the method of statistical pattern recognition for real-time information on the normalization, has achieved good results. Integrated decision-making information can reflect the mine pressure behavior, "the three elements of features (including mine pressure behavior of the time, location and extent), reveals the superincumbent stratum roof movement to promote the process of state and changes in the laws of underground pressure.(5) Research of Tingnan 106 fully mechanized caving face of the rock burst coal mine in Shaanxi province prediction applications has achieved good results, it illustrates with practical results of research papers.
