中文摘要：

山东省玲珑金矿有新、旧2条相互平行、相距10m左右的主运巷（主运输巷道），其下方为一垂直穿过的脉群采空区。为保护主运巷安全，在主运巷与采空区之间留有保安矿柱，并对空区进行毛石充填。由于主运巷下方受到非法民采的破坏，包括保安矿柱被盗采，导致新、旧主运巷均发生急剧的塌陷和变形破坏。为维持安全和正常生产，首先采取一系列特殊技术对旧主运巷进行加固治理，以恢复其正常运输通行能力。旧主运巷加固治理完毕后，运输线由新主运巷移至旧主运巷。按原方案，下一步应采取措施加固治理新主运巷，但由于经费困难，此步未能实施。大规模的新主运巷塌陷空区必将对已恢复运行的旧主运巷的稳定性产生重大影响。为监测这种影响，保证主运输线的安全，采用多点位移计监测、断面收敛测线、水准测量、应力监测和声发射监测5种手段建立塌陷治理区稳定性监测网。通过对多种手段获得的监测结果进行多元信息耦合分析，证实玲珑金矿旧主运巷采用符合岩石力学原理的高压锚注技术进行加固治理所取得的突出效果，同时对已加固治理的旧主运巷和未加固治理的新主运巷共存情况下主运巷的稳定性状态及其发展趋势作出评价，从而为主运巷下一步加固治理提供依据。

英文摘要：

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.
