Cross roadway reinforced support method for reinforcing top plate based on stack type support

The invention relates to a cross roadway reinforced supporting method based on a stack type support reinforced top plate, belongs to the technical field of roadway supporting, and solves the problem that in the prior art, the stability of a roadway is poor when a branch roadway is newly excavated. According to the cross roadway reinforced supporting method based on the stack type support reinforced top plate, before construction of a newly-excavated branch roadway, the stress distribution characteristics of surrounding rock of a roadway cross section, the plastic zone range and the surrounding rock point safety coefficient based on the Mohr-Coulomb criterion are obtained through theoretical calculation; on this basis, the range of a reinforced support area and the working resistance required by a stack type support are determined, the stack type support is installed on the roadway crossing section along the main roadway, a top plate of the roadway crossing section is reinforced through the stack type support
