Título Early detection of rock bursts
Título original Svoevremennoe obnaruženie vnezapnogo vybrosa [en ruso]
Información bibliográfica Feb. 1980, No.2, p.27-28. Illus.
Resumen The method, which is briefly described, relies on measurement of pressure pulses accompanying the shock wave and the use of a sensor to pick them up. Pulses caused by rockbursts and shotfiring operations were analysed and their characteristics (duration, amplitude, frequency) determined, permitting development of a transducer sensor which is not triggered by shock waves due to shotfiring in the neighbouring rock. The occurrence of suspicious pulses activates an alarm system.
