摘要：
The secondary coupling supporting technique on key parts (SCSTKP) is put forward. Based on the coupling state between supporting structure and surrounding rock of roadway, the key parts are divided into four types, and the characteristics of each type are described. The method to determine the optimum supporting time is also presented.
