Engineers (ISEE)

INDUSTRY STANDARD BLAST VIBRATION & NOISE MONITORING

PROCEDURES

The following standards should be applied when measuring blast-induced vibration and air overpressure (noise). These standards are based on the best practices recommended by The Vibration Section of the International Society of Explosives Engineers - 1999.

Part 1. General Guidelines

1. Qperators: Only personnel who have successfully completed a proper training course should operate monitoring equipment.

2. Calibration: The instrument manufacturer should annually calibrate recording units and sensors. Documenting certificates should be kept on file and copies should be provided to appropriate persons upon request.

3. Event Record Keeping: Hard copy reports and electronic file-copies of all event monitoring records should be maintained for all blasts. Operating notes should be programmed into the instruments, which should be printed monitoring records. These notes at a minimum should include the operator's name, date, time, place and other pertinent data specific to the monitoring location.

4. Trigger Levels: When employing instruments to operate in auto-trigger-mode, trigger levels should be set low enough to record blast effects. If expected levels of blast noise or vibration do not exceed minimum trigger levels, the instrument should be attended by an operator and turned on manually.

5. Documenting Monitor Location: In addition to event reports, an accurate method should be used to determine the monitoring location for later reference. Acceptable methods are 1) plotting numbered locations on scaled maps; 2) defining location with GPS northing, easting and elevation values; and 3) noting the name of the structure and the measured distance (+/- 1 ft) where the seismograph was placed relative to at least two identifiable reference points. Any person should be able to locate and identify the exact monitoring location at a future date.

6. Distance to Blast: The horizontal distance from the seismograph to the blast should be known to at least two significant digits. For example, a blast within 1000 feet would be nearest tens of feet and a blast within 10,000 feet would be measured to the nearest hundreds of feet. Where the vertical-to-horizontal ground slope ratio exceeds 2.5 tol, slant distances or true distance should be used and recorded in the monitoring records.

7. Processing Time: When instruments are used in auto-trigger and continuous-recording mode to record the effects of multiple blasts, the time between successive blasts shall be at least one (1) minute and seismographs shall be set to NOT automatically print out event records. These procedures should ensure that instruments have adequate time to save event data for each blast and reset to monitoring mode before subsequent blasts occur.

8. Memory Management: The instrument operator should know the memory or record capacity of the seismograph and ensure that adequate memory is available to store the event data from the blast(s) planned during that operating day.

9. Waveform Data: Instruments shall be set to save full waveform data for all monitored blast and digitally saved event files shall contain this data for use in further analyses if needed.

10. Instrument Setup Time: Equipment operators should allow ample time for proper setup of the seismograph, transducers and microphones. At least 15 minutes of time should be allotted for each setup location.

11. Securing cables: In order to prevent false triggering caused by wind-blown cables, the operator should secure suspended or freely moving cables from the wind or other extraneous sources.

Part II. Ground Vibration Monitoring

A. Sensor Placement

The sensor should be placed on or in the ground on the side of the structure towards the blast. A structure can be a house, pipeline, telephone pole, etc. Measurements on driveways, walkways, and slabs are to be avoided where possible.

1. Location relative to the structure: The sensor should be placed within 10 feet of the structure or less than 10% of the distance from the blast, whichever is less.

2. Soil density evaluation: The operator should avoid placing velocity transducers in loose or low-density soils. The density of the ground should be 'greater than or equal to the sensor density.

3. Sensor Level: Transducers should be placed so they are level or nearly level.

4. Sensor Orientation: Sensor blocks should be oriented so the arrow indicating the longitudinal direction is aimed at the blast location.

5. Monitoring when Access to Nearest Structure is not Accessible: Where access to a structure is not available, the transducers should placed at the accessible location closest the structure of concern and in line with the blast.

B. Sensor coupling

1. Sensor Coupling Methods: Based on expected acceleration determined from Chart 1, to avoid decoupling errors, the operator shall use the following methods to couple vibration transducers to the ground or structure.

a. Less than 0.2 g: No burial or attachment is necessary.

b. Between 0.2 and 1.0 g: Transducer should be attached to the ground with a spike or covered with a sand bag.

c. Greater than 1.0 g: Transducer should be buried, bonded to the ground or structure with stiff clay or putty, or some other method that should achieve firm attachment.

TABLE 1- Acceleration intensity (g's) based onestimated particle velocities and frequencies

2. Sensor Burial: When velocity transducers are buried the operator should employ the following methods.

a. Excavate a hole that is no less than three times the height of the sensor (ANSI

S2.47-1990, RI997).

3. Attaching Sensors to bedrock or hard Structural Surfaces:

within +/- l-foot of ground level (USBM RI 8969). This should only be used if burial, spiking or and bagging is not practical.

4. Other sensor placement methods: Use other methods as described below if disturbance of the ground is not possible.

a. Cover transducers with sand bags loosely filled with about 10 pounds of sand.

When placed over the sensor the sandbag profile should be as low and wide as possible with a maximwn amount of firm contact with the ground.

b. A combination of both spiking and sandbagging gives even greater assurance that good coupling is obtained.

c. Programming considerations

Site conditions dictate certain actions when programming the seismograph.

1. Ground motion trigger level: The PPV-trigger-level should be programmed low enough to trigger the unit from blast vibrations and high enough to minimize the occurrence of false events. The level should be slightly above the expected background vibrations for the area. A good starting level is 0.05 in/so

2. Dynamic range and resolution: If PPV is expected to exceed 10 in/s or frequency is expected to exceed 250 Hz, special sensors approved by the Vibration Specialist should be used to measure blast effects. In these cases, the Vibration Specialist should also determine a digital sampling rate that should provide accurate recordings.

3. Recording duration: Set the record time for 2 seconds longer than the blast duration plus I second for each 1100 feet from the blast.

Part III Air-overpressure Monitoring The following procedures should be used as possible when setting up instruments to measure blast-induced noise.

A. Microphone placement

The microphone should be placed along the side of the structure nearest the blast.

1. The microphone should be covered with a windscreen and mounted near the velocity transducers.

2. The preferred microphone height is 3 feet above the ground or within 1.2 inches of the ground. Other heights may be acceptable for practical reasons. (ANSI SI2.l8-1994, ANSI SI2.9-1992/Part2) (USBM RI 8508)

3. If practical, the microphone should not be shielded from the blast by nearby buildings, vehicles or other large barriers. If such shielding cannot be avoided, the horizontal distance between the microphone and shielding object should be greater than the height of the shielding object above the microphone.

4. If placed too close to a structure, the airblast may reflect from the house surface and record higher amplitudes. Structure response noise may also be recorded. Placing the microphone near a comer of the structure can minimize reflection of over-pressure energy. (RI 8508)

B. Programming considerations

Site conditions dictate certain actions when programming the seismograph to record air overpressure.

1. Trigger level: When only an airblast measurement is desired, the trigger level should be low enough to trigger the unit from the airblast and high enough to minimize the occurrence of false events. The level should be slightly above the expected background noise for the area. A good starting level is 120 dB.

2. Recording duration: When only recording airblast, set the recording time for at least 2 seconds more than the blast duration. When ground vibrations and air-overpressure measurements are desired on the same record, follow the guidelines for ground vibration programming (Part II C.3).

2.1.5 Identification of Stone Sources

The sources from which the Contractor proposes to obtain stone materials required for the features covered in these specifications shall be selected and identified to the Contracting officer well in advance of the time when the materials will be required in the work, a minimum of 30 days. The Contractor may select a source from the Virginia Department of Transportation list of approved sources of aggregates.

2.1.6 Testing And Approval For Rock Quality

The acceptability of the rock may be determined from existing test reports, service records from similar usage, by geologic examination of samples and of the quarry and/or by testing. The tests to which the materials will be subjected include petrographic analysis, specific gravity, abrasion, absorption, unit weight determination, sulfate soundness, wetting and drying, freezing and thawing and unconfined compressive strength, and such other tests as may be considered necessary to demonstrate to the satisfaction of the Contracting Officer that the materials are acceptable for use in the work. The minimum rock quality criteria which must be met are those specified in subparagraph Stone. In addition to the minimum criteria, other criteria determined from the tests or inspections listed above may be used to establish the acceptability of the stone. Approval of any source of stone shall not be construed as approval of all of the stone from that source. The right is reserved to reject certain localized areas, strata, or channels within the approved source when in the opinion of the Contracting Officer the stone is disintegrated, badly weathered, contains incipient planes of weakness or hidden joints/fractures, or is otherwise unsatisfactory for use in the work. All stone will be subject to inspection during loading at the source, at intermediate transfer points and at the site of work prior to placement.

2.1.7 Stone Not Meeting the Specifications

If, during the progress of the work, it is found that the stone being furnished and/or placed by the Contractor does not meet all the requirements of the specifications, the Contractor shall be required to furnish other stone of a quality acceptable to the Contracting Officer. Any stone rejected at the site of the work as not meeting the requirements of these specifications for quality, condition, size, gradation or otherwise shall be removed from the site by and at the expense of the Contractor, and stone of suitable quality shall be furnished and/or placed at no additional cost to the Government.
