The invention provides a method for supporting a deep soft rock roadway through high-pressure bolting-grouting coupling strong pier columns, which comprises the steps of high-prestress anchoring, surface guniting, high-pressure prestress bolting-grouting and pier column supporting and can be used for controlling large deformation of roadway surrounding rocks under complex conditions such as coal mine deep soft rocks and dynamic pressure. On the other hand, through large-tonnage strong support of the pier columns, stress borne by the roadway is greatly reduced, the deformation of the roadway is reduced, and coupling and cooperation of an active control method and a passive control method are achieved. The method is relatively simple and low in cost, large deformation of roadways of soft rock, deep high stress, strong dynamic pressure and the like can be effectively controlled, and beneficial exploration is provided.
