Research On Application Of Safety Isolation And Coal Mine Multi-Service Access

In recent years, the accidents of coal mine take place frequently, the solution of security production is desiderated. With the gradual progressing information level, the technology of remote monitoring and control will get well development in product system of coal mine.Based on the safety isolation of coal mines, Multi-Service Access System is one part of the Digital Coal Mine Gas remote monitoring system, It took underground automated production, control, monitoring and the system of multi-service access to integrated enterprise network platform and the security production situation under the ground can be monitored in the enterprise network at any time, as well as, the units above mine could achieve the commanding and scheduling of safety production.The paper firstly analyzes the status of coal mine safety, which a variety of coal mine monitoring systems were coexistent and the connection between industrial networks and enterprise networks is insecure. It proposed a solution about a multi-business integration and one-way transmission. Furthermore, it put forward a design that based on the safety of coal mines isolation multi-service access system under the overall framework, it projects and implemented the data integration and one-way transmission of the software named "Digital Coal Mine Gas Remote Monitoring and Control System" software. The whole narrated particular work with emphasis which in the software realization the author did: (1) Database design; (2) Solutions of the difficult technology above multi-service access and security isolation. Through to realized the process description, it introduces the key technology (DDE, OPC, FTP, UDP, multi-threaded). The programmed as the basis data access part of"Digital Coal Mine Gas Remote Monitoring System"of the"863 project". In the TingNan Coal Mine of the ZiBo Mining Group, the Digital Remote Monitoring System is conducted a field test and achieved the expected results. In the end, summing up the work, the paper analyzes the development trend of the remote monitoring and controlling technology and brings forward requirement for the system's perfection.
