In view of the complex construction technology and high support cost in the support engineering of deep broken surrounding rock roadway in Jinchuan No. 3 mining area, this paper takes the deep broken surrounding rock roadway in Jinchuan No. 3 mining area as the research object. Firstly, the numerical calculation models of double-layer spray anchor net and single layer spray anchor net add steel bar support are established, and the surrounding rock plastic zone, surrounding rock deformation, supporting bolt force and surrounding rock safety area under different support schemes are compared and analyzed. The results show that single layer spray anchor net add steel bar support can achieve the effect of double-layer concreting anchor mesh support. Finally, the field tests of two support modes are carried out in the 1330 sectional layered contact roadway, the deformation monitoring of the support test roadway shows that the roof deformation under the single layer spray anchor net add steel bar support is slightly larger than that of the double-layer shotcrete anchor net, the deformation of the two sides is less than that of the double-layer spray anchor net, and there is no failure in the test roadway. Numerical simulation and field tests show that it is feasible to replace the original double-layer concreting and bolting support with single layer spray anchor net add steel bar support under certain conditions in Jinchuan No. 3 mining area, which can meet the requirements of on-site normal production.
