For roof hazard of No.8103 fully-mechanized mining face in Tai'an Mine, forced caving technology with deep hole pre-splitting blasting was used on the working face to ensure the safety production of first weighting of the main roof and the integrity and promptness of the roof when falling, to improve the intervals of periodic weighting, and to relieve the huge load of periodic weighting of the main roof. Combined with auxiliary safety measures, the technology has achieved ideal effects.
