According to the rock characteristic and coal seam occurrence condition of 3208 material tunnel roof at Daxing Coal Mine

combining with modern theory of coal tunnel support technology

the combined support parameters of bolt

anchor cable

steel strap and mesh for the tunnel

are put forward; and daily tunnel pressure and support observation

such as roof separation

tunnel convergence deformation

anchorage stress of bolt (anchor cable) etc. have been done at a long time. The results of try-on and observation indicate that the application of bolt

anchor cable

steel strap and mesh combined support technique at Daxing Cola Mine soft-roof tunnel is successful and feasible. Suggestions about the support way of tunnel in samdwich and joint and cracked fake top are also presented.
