残留煤柱工作面受多个工作面采动影响，巷道围岩应力环境复杂、围岩自承能力差，支护难度较大。文章针对王庄煤矿43 M2残留煤柱工作面运输平巷现场条件，提出了“高强预紧＋分段控制”支护原则和相应的支护参数。现场观测表明：支护效果显著，为类似条件的巷道支护提供了参考。
殘留煤柱工作麵受多箇工作麵採動影響，巷道圍巖應力環境複雜、圍巖自承能力差，支護難度較大。文章針對王莊煤礦43 M2殘留煤柱工作麵運輸平巷現場條件，提齣瞭“高彊預緊＋分段控製”支護原則和相應的支護參數。現場觀測錶明：支護效果顯著，為類似條件的巷道支護提供瞭參攷。

Residual pillar mining influenced by multiple working face mining , roadway surrounding rock stress in surrounding rock , the bearing capacity is poor , support is difficult .Article 43 m2 residual coal working face in wangzhuang coal mine transportation roadway field conditions , puts forward the supporting principle “+high preload piecewise control” and the corresponding supporting parame-ters.Field observations show that the supporting effect is remarkable , and provides reference for the similar conditions of roadway sup-port.
