Abstract：There are two parallel main transport roadways in Linglong Gold Mine in which one is old and the other is new. They are apart about 10 m and both cross the mined-out area of a stripe-shaped mineral vein. Due to illegal mining under the roadways，which leads to the safety pillar at the bottom of the roadways being mined out，serious collapsing deformation and subsidence appeared in both transport roadways. In order to maintain normal production and safe operation，the collapsed area of the old transport roadway was firstly treated to recover its normal transport capacity. Some special reinforcing techniques were used for the treatment. After the completion of the reinforcement，the working transport line was moved from the new transport roadway to the old one. At the meantime，the large scale of collapsed area in the new transport roadway was not treated due to financial difficulty，which would give strong influence on stability of the old transport roadway. In order to monitor the stability of the working transport roadway，multipoint displacement measurement，cross-section convergence measurement，leveling measurement，stress measurement and acoustic emission measurement were carried out. The monitoring results showed that the stability of the old transport roadway was quite well in 4 years after it was put into operation，which indicates that the support effect of the special reinforcing techniques used for the old transport roadway is excellent. Due to lasting influence of collapsed area in the new transport roadway，remarkable deformation and local damage were later found in the old transport roadway. An assessment on stability status and its developing tendency was made out based on coupling analysis of monitoring information obtained by different monitoring measures. It provided a reliable basis for decision-making of further reinforcement of the main transport roadway.
