[Abstract]:Gas disaster, as one of the main disasters in coal mine in China, has been puzzling the safety production of coal mine for a long time. Based on the investigation and analysis of gas prediction method and early warning technology, the real-time monitoring data of gas emission in coal mine are used to reflect the characteristics of gas emission. The outburst prevention monitoring data is used as the research object. The relationship between the gas concentration variation characteristics and the real-time gas monitoring data and the anti-outburst monitoring data is described by the neural network method. The main research work is as follows: firstly, the basic theory and prediction method of radial basis function neural network (RBFNN) are introduced. The feasibility of its application in coal mine monitoring data analysis and the basic principle of mine gas prediction are analyzed. Secondly, according to the characteristics of actual mine monitoring data, the interpolation method is used to preprocess the measured data, and a prediction and warning model of gas concentration in fully mechanized coal mining face based on real-time monitoring data processing of fully mechanized mining face is established. The real-time prediction and early warning of gas concentration in mining face are realized. Thirdly, aiming at the inspection / monitoring data, the statistical characteristic parameters of the real-time gas monitoring data are extracted, and the prediction and early warning model of coal and gas outburst risk in the tunneling face is established, which is based on the fusion analysis of the inspection / monitoring data. Coal and gas outburst risk prediction and early warning. Finally, the prediction and early warning model is applied to the field analysis and verification of an example mine. The analysis results show that the prediction error is small and the prediction result is more accurate, thus ensuring the reliability of the early warning analysis. The gas prediction and early warning technology based on gas inspection / monitoring data processing is studied in this paper. According to the application and analysis of field measured data, it shows good applicability and can be used as an effective means to expand the function of coal mine safety monitoring and monitoring system. It has certain practical application value.
