针对潘一矿东井-842 m东翼1号回风大巷难以支护的问题,在分析该巷道变形破坏影响因素的基础上,结合高强锚注支护技术的特点,提出了以新型树脂药卷式中空注浆锚杆为基础的高强锚注支护体系。工程试验表明,该加固方案有效地控制了巷道围岩变形,试验取得了良好的支护效果,为淮南矿区其他相似条件下巷道围岩控制提供了参考依据。
針對潘一礦東井-842 m東翼1號迴風大巷難以支護的問題,在分析該巷道變形破壞影響因素的基礎上,結閤高彊錨註支護技術的特點,提齣瞭以新型樹脂藥捲式中空註漿錨桿為基礎的高彊錨註支護體繫。工程試驗錶明,該加固方案有效地控製瞭巷道圍巖變形,試驗取得瞭良好的支護效果,為淮南礦區其他相似條件下巷道圍巖控製提供瞭參攷依據。
