The application of microseism controlled blasting technique during construction, as well as the construction technique of the resin tensile anchor bolts, are introduced also.
Theoretical analysis and experimental results show that the method has the effect as same as Hall sensor in the event that ensure the DC motor start-up quickly and microseism, and no locked rotor.
The microseism source excitation model and the relation between the magnitude and vibration cycle
This paper emphasize in study of mechanism of vibration frequency for free site in microseism testing.
