Determination and experimental study on technical parameters of bolt-shotcrete support for deep rock roadway

In order to solve the problem of deep rock roadway stability control, a large-size three-dimensional numerical calculation model of “bolt support and concrete shotcrete layer” was established by means of numerical simulation and field industrial test. The control effect of bolt and shotcrete support...
