The bolt(cable)-beam-mesh combined support of the soft-rock coal roadways he ? 3-1coal seam is based on the evaluation of the ground stress in Mengzhuang Coal Mine of Wanbei Mining Group Corp., and Considering of technological conditions of the production, the parameters of the bolt-beam-mesh combined support have been determined according to engineering analogy and engineering measurement methods. Compared with the traditional U shape steel post support, the investment in supporting 1m roadway can be reduced by RMB 620 by the use of bolt-beam-mesh combined support, further more the bolt-beam-mesh combined support has such advantages as high construction efficiency, low intensity of work, good stability of supported roadway, remarkable economy benefit and high value of application.
