摘要
Abstract
In view of the complex stress and instability of the three fork roadway in the 2902 lower crossheading rock roadway section of Chensilou Coal Mine,a combined support way of"anchor rod+anchor cable+metal mesh+spray grouting support"is determined through force analysis of the triangular area of roadway three forks.The overall stability of the roadway surrounding rock is greatly improved,the subsidence amount of the roof is controlled below 0.07 m,and the convergence amount of the two sides is controlled below 0.06 m.关键词
