Abstract: Abstract: in recent years, with the increase of mining depth, pressure increases, especially the bottom area of the tunnel and cavern surrounding roadways by the mutual influence of intensive mining, superposition of stress redistribution, and surrounding rock with mudstone and sandy mudstone, poor cementation, bedding, joints, soft and broken eugeogenous. When the roadway is excavated, the floor drum is damaged repeatedly, and the traditional soft rock roadway floor reinforcement technology is difficult to effectively control. Through in-depth research and analysis, put forward the comprehensive control technology of soft rock roadway floor heave control technology, combined with the drum of grouted anchor prestressed reinforcement cage + + "" shape reinforced concrete beam and ladder bottom, and the field of engineering practice, after more than a year, has played a very good governance effect. Key words: soft rock roadway, dense area, stress, superimposed roadway, floor, drum, failure, grouting, reinforcement, full length of grouting, anchor cable, reinforcement cage, "a few" shaped steel bar ladder beam reinforcement.
