Abstract:According to the analysis of the pressure observation and deformation curves of different support types in very soft rock roadway, it can be obtained that the increase of bolt length deteriorates the support effect, and that grouting effect in surrounding rocks whose range is far smaller than broken zone is no less than that in large range . Therefore, based on theory, numerical simulation and in-situ practice, the concept of the reinforced -crust support structure, support mechanism, characteristics, requirement and several types are brought out by increasing support strength, reducing support range and choosing suitable time.
