Abstract: Aiming at the problem of long support time and inability to achieve parallel operation of excavation and support during the rock roadway excavation process in Zhaolou Coal Mine,multiple gradient support technology is proposed.Through FLAC^3D software numerical simulation and theoretical analysis,a reasonable multiple gradient support model is established.The support scheme includes three stages:roof support,upper side support,and lower side support,and the specifications and row spacing of anchor rods and anchor cables are determined in detail in each stage.The numerical simulation results show that this support technology significantly reduces the deformation amount of the roadway roof and two sides,and improves the stability and excavation speed of the roadway;In the actual construction of the central auxiliary transportation main roadway,by adjusting the support steps and time intervals,support parallel operations are achieved,and the self stabilization ability of the surrounding rock is played in maximum extent;The monitoring data from the deep hole peeping instrument show that after multiple gradient supports are implemented,the damage degree of the surrounding rock on both sides of the roadway is relatively small,the development of cracks is slowed down,and the support effect is significant,effectively maintaining the stability of the roadway.
