Abstract
This paper aims to explore the mechanical characteristics behind temporary support brack-ets in soft rock roadway.Based on the soft rock lane support theory,the study involves designing a tem-porary roadway support bracket;establishing a mathematical model to have the force analysis;and analy-zing the characteristics behind the surrounding rock stress and displacement in the soft rock roadway.The results show that with the the support of this bracket,the stress of the two sides and the shallow sorround-ing rock in roadway increases significantly;the deformation volume decreases significantly;and the sup-port effect is significant with the average movement of the top plate by 1.88 mm,and the average move-ment of the two sides by 2.3 mm.During the decline of the bracket,the force of the right half of bracket is significantly greater than that of the left half by using Adams software to have the dynamic analysis of the bracket,and the surrounding rock presents uneven deformation,which causes the bracket to be dam-aged by concentrated force.关键词
