DESIGN METHOD OF BOLT SUPPORT FOR COAL SEAM ROADWAY BASED ON GEOSTRESS
以地应力为基础的锚杆支护设计方法

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.
