Aiming at the difficulties in the support of high-pressure roadway due to the extension of extraction and the increase of ground pressure in Haizi Colliery,the authors present the combined support technology using shotcrete and bolting with bar and wire mesh in the design of rock roadway development,which effectively controls the deformation of surrounding rock and improves the support quality.
