Abstract The stability of stope wall rock and obsturator is a key issue for the safty of the second stage minimg in Jinchuan no.2 digging. As mining depth of the stope area and geopressure increase，stope wall rock and obsturator are of the possibility of serious yielding destruction and whole instability. In order to forecast the stability condition of wall rock and obsturator，a series of methods are applied to monitoring deformation，among which convergence monitoring is one of the main methods. The arrangement of laneway convergence monitoring net，monitoring project and monitoring result are presented，and some meaningful conclusions are obtained.

Key words： rock mechanics underground mining convergence deformation feature
