Abstract: Safety crossing ditch mining technology of shallow coal seam covered with thin bedrock is put forward by taking 22404-2 working face of Halagou coal mine crossing ditch as background.First of all,forecast the accidents that may occur during crossing ditch mining,and then take the appropriate technical measures to prevent accidents.Finally,analyze the application effect of technical measures.Production practice results show that the technology is successful and effective,which provides reference for mining in Shendong area with similar mining conditions.
