Abstract: Roof disaster is the main disaster of safe, efficient, green and intelligent mining of mines, taking the Qinglongsi Coal Mine in Xinmin Mining Area as the research object, through aerial remote sensing image analysis, surface geological survey, geological drilling, drilling geophysical logging, drilling cross-section ratio analysis, fine description of drilling core, rock mechanical parameters testing, surface settlement monitoring, working surface mine pressure data monitoring, mineral pressure data analysis and other technical means, comprehensive analysis of the types of hidden disaster-causing factors, spatial distribution and risk of coal seam roof. It is found that there are hidden disaster-causing factors such as hard roof plates, excessive deep trench mining, crushed soft-weathered bedrock roofs, thin bedrock of open pits, backfilling of open pits, large-area overhangs in goaf areas, and concentrated coal pillars in coal mines, and put forward corresponding prevention and control measures and suggestions for the above hidden disaster-causing factors. The research results provide geological guarantee for safe and efficient mining of coal mines, and provide reference for the analysis and evaluation of hidden disaster-causing factors on the roof of adjacent mines and similar geological conditions.
