Research On Early System Warning Of Gas Explosion In Coal Mine Based On Case Reasoning

The gas disaster has caused the serious losses to our coal production,and it is the leading cause of deaths in China coal mines NOW. The paper sends under the theory instruction in the gas explosion, three types of hazard theories and accident tree, It explained that the risk degree would be decided by the control of the second and the third types of hazard. If the coal mine production would like to reach a safe level. It required reliable facilities, reasonably organized, efficient management, and the safety consciousness of staff as well as a good safety atmosphere.The paper explores the framework of early warning systems about the gas hazard in the coal mine. Focus on the gas early warning systems modules, acts according to the actual situation to propose the prevention forecast gas concentration. Use the early warning of gas density to the early warning of gas explosion. And study tradition method and model use to forecast gas explosion. This paper proposed the thought that the early warning of gas explosion based on the case. And it gives the prototype about the early warning system of gas explosion based on the case inference. Has studied the important technology in the system: Case knowledge expression, case retrieval, case study and so on. According to the existing knowledge, uses theVB6.0 and the OFFICE ACCESS2003 development the early warning system about inference gas density based on the case inference. According to the changing of the gas concentration. Reference former knowledge,screening the disaster which possibly has and the guard measure which needs to carry on. Provides the advantageous policy making support for the policy maker. The data for gas warning systems from various monitoring devices, Thus keep monitor and control equipment stable and reliable is essential to early warning system.. In the early warning of the equipment's reliability,Take the reliability as the central plan of the equipment service, Take the maintain of equipment's reliability ahead of the early warning of the equipment's reliability, and has given method to computation the repair cycle, and does the preventive maintenance work according to the above.
