Study Of Ir Detection And The Treatment Technology Of Coal Outcrop And Slag Fire In Ulan Coal Mine

Coal spontaneous combustion fire is one of the major disaster in the mine, Spontaneous Combustion Fire is a phenomenon that in Coal Outcrop is, the coal not mining in the natural environment due to oxidation and heat accumulation is caused burning by coal seam outcrop; The loose coal heap caused by private dredging and casual mining are easy to form slag coal spontaneous combustion fire due to oxide accumulation. The fire area in the ulan coal mine, is the outcrop coal and slag coal spontaneous combustion fire zone caused by outcrop stripping,digging and small kiln mining.According to the actual situation in the Ulan Coal Mine Fire, This article will study on the fire detection and comprehensive control technology in the outcrop coal, slag coal of the coal spontaneous combustion. First, according to the factors affected by coal spontaneous combustion, analyze the reasons and factors caused by outcrops,slag coal spontaneous combustion, combined with the actual situation in the fire zone, propose the overall fire prevention and control technical program of "separation of oxygen, temperature control area, control the proliferation of the fire," Secondly, analyze the actual situation of coal spontaneous combustion in the fire, detect the high-temperature range of the fire by Infrared Imager, the analysis show that the infrared detection method can detect the Java platform range of natural fire zone; then ,for Ulan mine fire area in accordance with its surface associated with a larger apparent surface ignition characteristics, but also vulnerable to the effects of mining shaft, by halogen track SF6 gas leak on the surface leakage channel analysis of surface air leak on the underground gas output of CO, and take the appropriate Fire Fighting Measures plugging achieved significant results; again, according to the actual Ulan Coal Mine Fire District as well as polymer gel plugging, filling, cooling and other characteristics that determine the gel-based fire extinguishing technology, mechanical peeling, cover supplemented by technical measures, through the comprehensive management, after the implementation of the program to get full control of the fire area; Secondly, analyze the actual situation of coal spontaneous combustion in the fire, detect the high-temperature range of the fire by Infrared Imager, the analysis show that the infrared detection method can detect the range of the outcrop coal, slag coal of the coal spontaneous combustion fire zone; Then,according to Ulan Coal Mine fire district and the associated largely with the surface, surface ignition characteristics obvious, characteristic affected vulnerably by the mining shaft, analyze the effects of surface leakages to the CO gas generation underground, measure the surface leakage channel by the amount of halogen tracer gas SF6 ,and take the appropriate measures plugging fire, has achieved remarkable results; again, according to the actual situation in the Ulan Coal Mine fire district and the plugging, filling, cooling and other characteristics of the polymer gel ,determine the technical measures that is the gel-based fire extinguishing technology, mechanical peeling, cover supplemented, through the comprehensive management, after the implementation of the program ,has gotten the full control of the fire area; Finally, through the analysis of monitoring the harmful gases in the fire district , shows that it can put out the slag coal spontaneous combustion fire district that takes the measures based-on the polymer gel fire prevention technology . It is meaningful reference.that control the outcrop coal and slag coal spontaneous combustion fire in the study of this paper.
