Application Research of Ground Pressure Coupling Monitoring Network for Deep Mining in Sanshandao Gold Mine

Aiming at the problem of surrounding rock stability and ground pressure induced by deep mining in Sanshandao Gold Mine, coupling monitoring network composed of convergence monitoring section, rock deep displacement monitoring section and stress monitoring section is arranged, combined with the tunnel monitoring theory and project actual conditions; satisfactory data are obtained through long-term monitoring work and practical application. On the basis of monitoring results, activity law of ground pressure is well studied. Achieved results reveal the deformation and stress change of surrounding rock cased by backfill mining are relatively small; The coupling monitoring network is engineering practicable, which meets the needs of rock stability prediction of Sanshandao Gold Mine during its deep producing period.
