Zusammenfassung:The invention belongs to the technical field of roadway surrounding rocks, and particularly relates to a soft coal seam mining roadway surrounding rock deformation control method influenced by dynamic pressure. The soft coal seam mining roadway surrounding rock deformation control method comprises the steps that firstly, disturbance to a roadway is reduced through shallow digging reinforcement; then surrounding rocks are sealed through timely guniting, and disturbance to the surrounding rocks is further reduced; then a bottom plate is sealed in time to prevent bottom heaving; meanwhile, surrounding rock weathering is prevented, and surrounding rock weathering is prevented; and then grouting reinforcement is carried out on a roadway protection coal pillar, roof cutting pressure relief is matched, finally, mine pressure is monitored in time, and reinforcement is carried out in time when problems occur. The purposes of keeping the integrity of the surrounding rocks, preventing the weathering damage of the surrou
