"Analysis of bolting failure in deep mining roadway and support counter" by Yiguo Ning, Shuangwen Ma et al.

Aiming at the problem of holt support failure caused by surrounding rock deformation in deep mining roadway,a method was pro¬posed to reduce the bolt breakage by improving the bolt stress state, changing the anchoring mode and optimizing the shape of rod body. On this basis, a new rebar anchor rod with a new shape and structurewas designed. Laboratory tests show thatthe average pull-out force of the right-hand bolt, the left-hand bolt and the high strength bolt with large rib spacings are 136.9 kN, 106.1 kN and 147.6 kN, andthe large-rib spacing high-strength bolts absorb energy better result. Before the field test, the surrounding rock structure of the return air roadway was detected, including roof drilling and loose circle testing. The final roadway support scheme was determined according to the detection results of surrounding rock structure. The original supporting scheme and full bolt supporting scheme were adopted for the return roadway, and the roof separation and bolt stress ....
