Application Research of Rock Coupling Testing System for Underground Engineering in Sanshandao Gold Mine

Abstract:

Rock instability and failure disasters are now common engineering-geological problems of underground engineering. The evaluation of stability of surrounding rock is a complicated uncertainty system problem, which needs various different research means. Rock coupling testing system composed of loose circle testing section, convergence monitoring section and multipoint displacement monitoring section is arranged at-600m level of Sanshandao gold mine; deformation law of roadway surrounding rock is well studied through long-term field testing and monitoring work. Achieved application results reveal overall stability of rock mass in gold mine deep area is relatively good, current impact caused by roadway excavation is not obvious. Coupling testing system is engineering practicable, which can meet the demand of rock stability evaluation study of underground engineering in Sanshandao gold mine.
