Research On Coal And Gas Outburst Based On Electromagnetic Radiation

Coal and gas outburst is a dynamic phenomenon of coal mine with sound and violent energy effect.Under the joint action of ground stress and gas,the phenomenon of broken coal rock and gas from the coal rock mass to the space of coal mining suddenly overflowing.The area and risk of coal and gas outburst is still expanding,so the problem needed to solve is how to predict in advance accurately.In the laboratory experiment,characteristics of the mining area coal sample electromagnetic radiation is analyzed.The mining area coal sample can generate electromagnetic radiation,and coal sample in the process of deformation under load,the intensity of electromagnetic radiation is positively related to the magnitude of the loading stress.According to the experimental results and analysis of the relevant data,the coal and gas outburst is a sudden,but there are precursors in the outburst,electromagnetic radiation,which is one of the precursors.The electromagnetic radiation method can be used to predict coal and gas outburst.On the basis of using the method of fuzzy recognition method,the sensitive index and critical value of electromagnetic radiation method are determined,provide the judgment to establish the electromagnetic radiation neural network model to predict coal and gas outburst.On the basis of the adaptive principle,the Elman neural network is improved.The improved neural network model is constructed and applied to the electromagnetic radiation of coal and gas outburst danger prediction,and combined with historical data using MATLAB simulation experiment.Results show that compared with other forecasting models,the prediction accuracy of the model is higher,stronger generalization ability,can effectively realize the danger of coal and gas outburst dynamic trend prediction of electromagnetic radiation.It has higher practical value,and also provides a new way of thinking for coal mine coal and gas outburst danger prediction.By using micro computer hardware and related knowledge,this paper researches a kind of high efficient new handheld comprehensive monitor on the basis of in-depth investigation in the traditional monitoring system and special and complexity of the coal mine environment comprehensive consideration.Hardware design mainly introduces informationprocessing module,power supply module,etc.And this paper puts forward the improvement to the hardware anti-interference methods,and has made the corresponding research on the software parts.
