The Detection And Control Technology Research Of Spontaneous Combustion Dangerous Region Of Endosed Area Of Resources Integration Mine

Along with the coal industry scale, intensive, mechanization development, Shanxi ProvinceImplement the mine enterprises mergers and implement strategies of Integration of coalresources but the resources in the mine integrated technical transformation and mining stage willface many technical issues. Among this how to control the small coal mine before integrationwhich with large area of spontaneous combustion dangerous region, become to the key work offire district management in the resources integration coal mine. This research studies thespontaneous combustion causes and its characteristics of the small coal mines before Shuiquancoal mine integration, use the ground isotope measuring radon detection technology to detect thesituation of the spontaneous combustion region, according to the situation of the spontaneouscombustion region of Shuiquan coal mine, identify the control technology measures which couldbe suitable for the spontaneous combustion hazardous area for such enclosed area of resourcesintegration mine.In the experimental study, join use of temperature-programmed devices and infraredspectroscopy, and master the change rule of basic parameters during the oxidation combustionprocess of coal according to the spectral signature of generated mark gases. Analysis of the mainfactors of spontaneous combustion of small coal mines which is before integration of resources,to provide the basis for the work of controlling combustion area. In the field detection study, useground isotope radon detection technology to detect the area of spontaneous combustion.Through data analysis, initially identified the range of spontaneous combustion region, fire trenddevelopment direction and fire trends center position.Based on the above research, design using surface boreholes filling Carbon dioxidetechnology to control spontaneous combustion area, establish the Carbon dioxide filling system,and determine the reasonable location of the ground drilling according to the explored situationof combustion area, which make the control of a large area of spontaneous combustion region tobe more systematic and efficient. The result of this study haves the certain reference value andsignificance to the control work of a large area of spontaneous combustion region in similarenclosed area of resource integration coal mine.
