Blasting Vibration Monitoring Equipment Ground Vibration Monitor
![]()
Blasting vibration monitorng equipment collects vibration signal from blastic site without human prescense automatically. There is no sort of setting to be done. Just keep in place an switch on - data recording happens one the machine senses vibration. data will be saved when the vibration stops which can later be retrieved for further analysis and study.Blast monitoring is required in many applications related to explosions, like mining, excavations, and demolition sites.
Why Monitor Your Blasting Project?
Controlled blasting activities are used extensively. In urban areas to create underground parking garages, or bedrock foundations, in cross urban areas during road and bridge construction and in more rural areas where quarries and mining operations are found. Regardless the area blasting explosives create strong vibrations that can potentially damage nearby homes, buildings, sewer lines and other structures. Blasting can also cause air overpressure which produces a force of air. This force of air can set off car alarms and damage windows. Even when these activities are performed under best-case scenarios, they can cause concern to neighboring buildings and homeowners.
Understandably, when china cabinets rattle or car alarms go off, people are often led to believe that their property is being damaged by the nearby construction activity. This can lead to formal complaints which can result in project suspensions and even fines. Noise levels can also be a health and safety concern for your workers.
Sensor arrangement principle:
- Before you begin,number the sensor and your monitoring-point；
- Clear the installation position's foundation surface,the sensor and your monitoring-point should be a Rigid Contact.；
- The arrow direction (horizontal radial x) of the sensor points to the explosion center, which is placed horizontally, and the installation angle error is not more than 5 °；
- Install the sensor on the sand medium, fix the sensor on a steel bar (diameter less than 10 mm) that penetrates the loose layer on the ground, and the steel bar extends out of the ground no more than a few millimeters, so it is necessary to ensure the close contact between the steel bar and the sand；
- When the sensor must be installed below the ground, in order to minimize the distortion caused by the combination with the ground, the buried depth shall be at least 3 times of the main size of the sensor.
