The Research Of Monitoring And Appraising Method In Spontaneous Combustion Of Coal

On the basic of analyzing and research of the rule and measures spontaneous combustion of coal, this paper further investigates the method and technological system of dangerous monitoring and appraising in spontaneous combustion of coal. First of all, analyze the data that coal oxidize and intensify which was determined through laboratory, make clear the emergence rule of the marks gas in different stages that spontaneous combustion of coal; through use the analytical method of regulation, draw the experiential formula of the functional relation of coal temperature and CO index gas, etc. On that basis, Analyze the parameters and index system of monitoring in spontaneous combustion of coal, which mainly includes temperature and CO, alkenes and olefin, etc; put forward the method, index system and the standard of dangerous appraisal about spontaneous combustion for coal. After, probe into the analytical method of technological and economic about prevention and extinguishments for fire, and put forward the method of appraisal and optimum seeking about the scheme to prevention and extinguishments for fire. At last, developed" the dangerous appraisal of spontaneous combustion of coal and the analysis system of technological and economic". This system can combine application with the monitoring system of spontaneous combustion for coal, which can go on dangerous monitoring, appraisal of the coal spontaneous combustion and the optimum seeking scheme of prevention and extinguishments for fire; which may alone application too, through input the concentration information of CO, etc, to assess hazard of the spontaneous ignition and seek the optimum scheme of prevention and extinguishments for fire, etc.The achievements in research of this paper have been practised successful in No, 2 Coal Mine, lining and make good result.
