Study of Soft Rock Roadway Support Technique
Soft rock prevalent in coal-bearing strata in China, a lot of soft rock is buried deep in the larger role of high stress by the formation, and maintenance of the roadway is very difficult to dig. Therefore, the soft rock tunnel in the control theory and practice of in-depth study on the maintenance of soft rock and coal mine production safety have important theoretical and practical engineering value. Based on the characteristics of soft rock roadway analysis, and theory and method of supporting the research, choose the right type of support and supporting means, surrounding rock deformation control, reduce destruction of surrounding rock strata behavior, to take reasonable supporting effective technical control of roadway deformation and maintain the stability of surrounding rock. On the roadway approach to the design support for soft rock tunnel problems, combined with the practical application of steel mesh and anchor design support system anchorage system and deep surrounding rock formation deep control system, calculation of parameters of rational support And the corresponding recommendations and measures, and achieved good results.
