Abstract: Taking the fire-threatened mines in the shallow buried coal seam of the Jurassic coalfield in northern Shaanxi Province as the research object, the high-resolution UAV visible light and thermal infrared dual-light low-altitude remote sensing, handheld infrared thermal imager, wind speed measuring instrument, spherical bladder sampler, bundle tube detection and sampling, gas chromatography, borehole temperature measurement, borehole peeping and other technical means are used to comprehensively carry out rapid exploration of hidden disaster factors in the sky, ground, hole and underground comprehensive mining work surface, closed wall, roadway and other potential air leakage channels. We systematically summarize the types and characteristics of hidden disaster factors in ground, hole and underground air leakage channels of shallow buried coal seam in Jurassic coal field in northern Shaanxi province, construct a four-in-one “sky-ground-hole-well” rapid investigation technology system for hidden disaster factors in shallow buried coal seam coal mine air leakage channels, and apply the technical system to the fire-threatened Dequan Coal Mine for the exploration, quickly determine the type of air leakage channel, spatial distribution characteristics, combine with the fire prevention project to achieve the rapid extinguishing of the fire area and the overall rapid control of the temperature of the hidden high temperature area of the coal mine to ensure the safe, green and efficient mining of the mine.
