Monitoring the convergence deformation of roadway surrounding rocks is necessary for ensuring construction and extraction safety. In addition, it can also assist the stability evaluation of the underground mine roadway. This paper analyzes the advantages of a tunnel monitoring system—Bassett Convergence System. Based on this system, the tunnel cross-section convergence deformation continuous monitoring system “MineTCS” was researched and developed for underground mining roadway. The system can continuously monitor the convergence deformation under the condition without manual intervention. Compared with the Bassett system, it is more suitable for complicated engineering environment in underground mines. The application results obtained in Baoguo Iron Mine indicate that the roadway support costs were saved, the safety of the technicians was guaranteed and the efficiency of measurement was significantly improved at the same time. The improved system can accomplish the task of monitoring the convergence deformation of underground roadway. Moreover, it can also support the design of supporting scheme and risk warning. Therefore, the research results have broad application prospects in the future convergence deformation monitoring of underground mine roadway cross section, risk early warning and so on.
