The invention provides a deep well
coal mine roadway surrounding rock grading support construction method which comprises the following steps: carrying out
geological survey and ground exploration on a to-be-tunneled area, and determining the distribution position of a joint stratum in the to-be-tunneled area; performing advanced detection on the to-be-tunneled area according to the distribution position of the joint stratum to obtain a rock
mass of the to-be-tunneled area, and determining geological characteristics and
structural integrity characteristics of the rock
mass; according to the geological characteristics and the
structural integrity characteristics of the rock
mass, roadway surrounding rock grades are determined, the roadway surrounding rock grades comprise a plurality of grades, a supporting scheme matched with the roadway surrounding rock grades is determined, and supporting operation is carried out on the excavated deep well
coal mine roadway; and carrying out displacement monitoring on the supported roadway surrounding rock until the displacement of the supported roadway surrounding rock converges, and completing the support. The roadway surrounding rock can be graded, the supporting scheme can be correspondingly adjusted, the supporting efficiency is improved, and the stability and safety of the roadway are effectively improved.
