The two crossheadings in 20128 working face of A Coal Mine are both covered tunnels,using anchor shed combined support.To ensure that the support achieves the design effect,it is necessary to demonstrate the reliability of anchor shed support.This paper discussed the layout and mining methods of working face tunnels,demonstrated the reliability of anchor shed support from multiple aspects,and demonstrated the reliability of shed support.The results indicate that the safety and reliability of the combined support design of the crossheading anchor shed in 20128 working face are good,and it can meet the requirements of the working face support.
