By investigating the rockbolt, net and sprayed concrete supporting in the roadways of the second mining section of Xiao Guanzhang Iron Mine, authors found high stress around roadways, large rock distortion and fragmentized rock under the influence of mining action. The failure mechanics and occurred some problem of sprayed concrete were analyzed in theory, then the roadway supporting form was redesigned for this mine, i.e. , high- strength, pre -stressed rockbolt and net supporting without sprayed concrete. The in- situ experiments showed that the redesigned roadway supporting form can achieve good result, meet the needs of the engineering, furthermore, economic and societal benefit was very remarkable.
