This article analyzes the roof fall accident of Baojishan Coal Mine 704 transport gateway. And based on the "high-dipping, high stress, broken surrounding rock, compound soft top" geological conditions of this mine, the bolting extrusion reinforced arch and surrounding rock reinforcement principle are combined. Based on the support quality detection and mine pressure observation data, the engineering analogy method is used for dynamic supporting design to determine the supporting parameters; optimized improvement measures are put forward in roadway support scheme design, roadway cross section selection, construction technology, instruments and the supporting material and are applied in the site, to effectively control the deformation of roadway surrounding rock. Significant technical and economic effect has been achieved.
