采空区顺槽马丽散锚注加固试验与应用分析

Experiment and Application Analysis of Marithan Anchor Grouting Reinforcement in Crossheading of Goaf

主要把阳煤一矿81301的工作面作为研究分析实例,在该工作面采空区侧的回风巷回采的过程中,需要于掘进施工带、全锚索与网联合的基础上,通过马丽散对回风巷的侧煤柱实施锚注加固,以便对顺槽两帮变形与收敛进行控制,确保回采工作能够正常的进行。

Taking 81301 working face of Yangquan coal mine as a study case, in return airway recovery process of goaf in working face, based on the combination of tunneling belt, anchor cable and net, the grouting reinforcement by Marithan is constructed for side coal pillar in return airway to control deformation and convergence of crossheading, ensuring the normal work of mining.
