以朱集东煤矿埋深为900余m的1121（1）工作面轨道巷开展“一巷两用”扩刷修复为工程背景，根据工程现场观测的实际反馈情况结合围岩稳定性和扩刷机制理论，针对扩刷期间围岩变形、应力变化等特点，制定合理的沿空留巷扩刷原则，通过合理可行的施工工序与优化参数选择，联合主被动支护，提高巷道支护强度，确保巷道成功修复并安全使用。
以硃集東煤礦埋深為900餘m的1121（1）工作麵軌道巷開展“一巷兩用”擴刷脩複為工程揹景，根據工程現場觀測的實際反饋情況結閤圍巖穩定性和擴刷機製理論，針對擴刷期間圍巖變形、應力變化等特點，製定閤理的沿空留巷擴刷原則，通過閤理可行的施工工序與優化參數選擇，聯閤主被動支護，提高巷道支護彊度，確保巷道成功脩複併安全使用。

It is verified in the background of the gob-side entry retaining reparation engineering of 1121 ( 1 ) coal mining face in Zhuji mine around 900m underground to carry out"a dual-lane"Enlargement repair.Combina-tion of surrounding rock stability and Enlargement mechanism theory,based on the actual situation of the project site observation feedback, deformation and stress of roadway surrounding rock before reparation were analyzed by field measurement and theoretical method:We develop reasonable principles for gob-side entry retaining reparation engi-neering.By reasonable and feasible construction process and the optimization of parameter selection, combined with active and passive support to improve the roadway strength to ensure repair the roadway successfully and make it safe to use.
