Hidden disaster-causing factors in coal minesdenote the geological structures and unfavorable geobodies that are concealed in coal seams and surrounding rocks and may cause mine disasters during mining. Methane and radon are common harmful gases in coal mines, and their abnormal release is often accompanied by hidden disasters like unfavorable structures of coal seams and gas accumulation. With the Xinyuan coal mine in Yangquan City as the study area, this study selected two geochemical indices based on the microseepage mechanism:Methane and radon, which are highly sensitive to hidden disaster-causing geological factors. Building on the dynamic monitoring data of methane and radon in free hydrocarbons at 408 points, and the area survey data of methane in free and acid-hydrolyzed hydrocarbons at 416 points and soil radon at 651 points, this study obtained the geochemical characteristics reflecting the distributions of disaster-causing factors like the underlying water-bearing fracture zones, coal bed methane see page zones, microstructural fracture zones, and collapse column surround zones. Moreover, this study conducted joint exploration and analysis combined with the wide-field electromagnetic method, completing the verification and identification of hidden disaster-causing factors related to structures and gas accumulation in coal mines. Furthermore, it delineated the distribution sections of potential disaster-causing factors in the study area. This study demonstrates the applicability and practicability of the hydrocarbon microseepage theory in the exploration of hidden disaster-causing factors in coal mines. It also lays a foundation for the extensive application of methane-radon geochemical indices in the survey and exploration of hidden disaster-causing factors in coal mines, thus holding critical significance for enhancing the safety of coal mine production.
