|
|
|
|
Abstract A dynamic bolt support design method for coal seam roadway is reported. The method includes the steps of geostress test，geomechanics evaluation，initial design，in-situ measurement，information feedback and design revision. Other methods like numerical stimulation，in-situ test and monitoring，and engineering analogy are also used to optimize the design.
