Embodiment Construction
[0051] Through the following examples, combined with Figure 1-8 , the technical solution of the present invention will be further specifically described. A method for controlling damage of slope pre-splitting blasting excavation based on blasting vibration test of the present invention comprises the following steps:
[0052] (1) Three-way vibration velocity sensor is used for monitoring. In the specific monitoring process, a three-way velocity sensor (which can measure vertical, horizontal radial and horizontal tangential vibrations at the same time) is arranged at the same measuring point of the key monitoring part, and fixed on the required monitoring point with plaster or other adhesives. The part, and then connect the vibration signal self-recorder with it. When the blasting vibration signal is transmitted to the measuring point, the vibration signal self-recorder automatically records the signal. After the explosion, use the blasting vibration analysis software that c...
