摘要
本文从支架变形破坏的原理入手,采用理论与现场试验结合的方法;根据巷道围岩表面顶底板位移速度及位移量、两帮位移速度及位移量、底臌量等,合理地选择回采巷道的支架形式,取得了良好的效果。
This article starts with the bracket distortion destructive, adopts the method of theory and locale experiment; bases on the surface variety speed and measure of top and soleplate and two side surrounding rock and so on, chooses the form of bracket and has a good effect.
