以王庄煤矿支架换装硐室为例,根据现场观测及围岩钻孔窥视,分析了超大断面硐室围岩破坏的5种类型;为了解决超大断面硐室围岩破坏问题,根据王庄煤矿地质工程条件,提出了“锚网索喷+浇注钢筋混凝土+全断面注浆”支护技术方案;通过现场工业性试验和围岩表面变形观测可知,该支护方案对于控制超大断面硐室围岩变形具有很好效果,能够保证硐室长期的正常使用。
以王莊煤礦支架換裝硐室為例,根據現場觀測及圍巖鑽孔窺視,分析瞭超大斷麵硐室圍巖破壞的5種類型;為瞭解決超大斷麵硐室圍巖破壞問題,根據王莊煤礦地質工程條件,提齣瞭“錨網索噴+澆註鋼觔混凝土+全斷麵註漿”支護技術方案;通過現場工業性試驗和圍巖錶麵變形觀測可知,該支護方案對于控製超大斷麵硐室圍巖變形具有很好效果,能夠保證硐室長期的正常使用。
