摘要
选择基于地面钻探的温度探测法和气体分析法,探测德泉矿1-2煤层房采区火区位置,结合灰色关联度计算分析,得出CO/CO2、CO/O2和CO指标与火区温度有较高的关联度,验证了火区探测结果的准确性,并预测出火区发展趋势,为类似陕北浅埋房采区煤自燃火区探测提供了新的思路。
The temperature detection method and gas analysis method based on surface drilling are selected to detect the fire area of 1-2 coal seam mined by room and pillar in Dequan mine, Combined with the calculation and analysis of grey correlation degree.The results show that the indexes of CO/CO2, CO/O2 and CO have a higher correlation with fire zone temperature.The accuracy of fire detection results is verified, and the development trend of fire area is predicted, which provided a new idea for the detection of coal spontaneous combustion fire area similar to the shallow room mining area in Northern Shaanxi.
