Philip Best conducts private home Blast Vibration Monitoring number 2. The results of this indicates much stronger
vibration than what is measured outside on the ground by the Quarry Vibration monitoring.
Philip Best receives details of the 1.6 metre diameter water grid pipeline which passes through the Botanic Gardens
only 100m from the resource processing & basting zone plus 350m from an existing blast face.
Local residents are concerned that if the pipeline has been or becomes damaged by blast vibrations, then the repair
process will devastate the area and uproot botanic gardens trees and flora.
The location of this pipe is now marked on our KRA-42 diagram which contains our other data.
Philip Best conducts Blast Vibration Monitoring number 3 on a home. The results of this indicates much stronger vibration
than what is measured outside on the ground by the Quarry Vibration monitoring.
David Hassall and Philip Best meet with Michael Berkman and Jonathon Sri at the Maiwar electorate office to discuss
the Mt Coot-tha Quarry and our report.
It was decided that a new report be created which does not contain the same committee proposal as the previus one
did.
Philip Best conducts Blast Vibration Monitoring number 4 on a home. The results of this again indicates much stronger
vibration than what is measured outside on the ground by the Quarry Vibration monitoring.
Philip Best contacts a Statistical Consuntalt asking them to analyse our Blast Vibration Data spreadsheet,
The following results were obtained for Mt Coot-tha Rd (MCR), Sussex St (SST) and Richer St (RST) for after blast
number 600:
Mean value for MCR/RST = 3.69 times stronger. MCR/SST = 2.66 times stronger.
Median value for MCR/RST = 3.63 times stronger. MCR/SST = 2.69 times stronger.
The question remains: Why (for 600 blasts until Nov-2011), did the BCC only do permanent blast monitoring at more
distant locations, where the vibration levels are much less.
Clearly the blast vibration reporting to the Qld Government was misrepresented for 600 blasts, because they did
not do permanent monitoring at 159MCR,
Permanent monitoring at the unused address of 159 Mt Coot-tha Rd, by the BCC, only began after strong protests from
the local residents.
Philip Best and other residents continue to conduct a total of 10 Blast Vibration Monitorings on their private homes.
The results of this are consistent with earlier private home blast vibration measurements which indicates a 2.5 times stronger
vibration than what is measured outside on the ground and reported to DES by the MCQ Vibration monitoring.
