Coal mines in China are mainly underground mining, a large number of roadways need to be excavated underground, and roadway support is adopted to keep the roadways smooth and surrounding rocks stable, so that the method has important significance for coal mine construction and production. The basic purpose of supporting the roadway is to alleviate and reduce the movement of surrounding rocks, so that the section of the roadway is not excessively reduced, and meanwhile, the scattered and damaged surrounding rocks are prevented from falling. The roadway supporting effect is not only dependent on the supporting force of the support, but also influenced by a series of factors such as the properties of surrounding rocks, the mechanical properties (supporting force and flexibility) of the support, the installation density of the support, the time of installing the support, the installation quality of the support and the contact mode (point contact or surface contact) with the surrounding rocks. Generally, in order to make the roadway support play a positive role in regulating and controlling the deformation process of the surrounding rock, the support is installed before the surrounding rock loosens and is damaged, so that the support and the surrounding rock play a bearing role under the condition that the surrounding rock still keeps self-bearing force, but the support is used for bearing the weight of the caving rock block under the condition that the surrounding rock loosens and is damaged and the self-bearing force is almost completely lost. That is, the support and the surrounding rock should be made to carry together under mutually constrained and interdependent conditions.
