Monitoring critical stress conditions in mines and tunnels - using geophones and staggered frequency-time signal distribution evaluation

The method is for monitoring critical stress conditions, esp. in large geological layers of mining and tunneling constructions, enables the accuracy of measurement to be increased w.r.t. conventional methods in combination with equivalent or reduced cost of measurement equipment. Seismoaconotic sign...
