Based on surrounding rock geomechanical conditions of 9# seam in Gaizhou Coal Industry, mechanical tests performed in filed core-drilling method laboratory, and theoretical calculations, this paper propose practical measures for safety technology combined with engineering analogy method to determine support program. The results showed that roof roadway squat is smaller, which can meet the engineering requirements and effectively resolved open-off cut support problems in broken mudstone roof.
