• individual wall panels — 20 Hz to 40 Hz; • ceilings — 15 Hz to 30 Hz (the form of the roof structure in the Wambo house is not known, and possible shorter framing member spans result in higher frequencies). These frequencies are relevant for blast design in that, if a ground vibration is similar to a characteristic building frequency, the action can be greatly magnified. Theoretically, a maximum amplification of 50× is possible at resonance for a single-degree-of-freedom structure and structure amplifications of more than 20× have been measured during blasting events in or near Hunter Valley mines. 3 2 THE ASSESSMENT 2.1 Monitoring Recording instrumentation was set up on two occasions when blasting was being carried out in the Homestead Pit, on 16 December 2011 and 17 February 2012, with ground vibration PPV levels recorded at the Homestead monitor of 4.07 mm/s and 1.68 mm/s respectively. Instrumentation was set up in the house on the first occasion and the first floor of the kitchen wing on the second. Figure 1 shows the sensor locations for the two events. Figure 1: Positions of accelerometers for the two monitored events. The New House was monitored on 16 December 2011 and the Kitchen Wing, first floor, on 17 February 2012. The wall mounted accelerometers were, in each case, mounted at the tops of the walls. The numbers relate to the vibration recording data and are the channel numbers used on the recorder. ( Base drawing from EJE Architecture) 2.1.1 THE NEW HOUSE (16/2/2011) Three accelerometers were set up in a front room of the new house where the wall and ceiling dimensions were judged to be of a size which might make them vulnerable to out-of-plane resonant vibration at the expected blast wave frequencies: one sensor was fixed near the middle of the ceiling, one just below the ceiling on the front wall and one just below the ceiling near the middle of the wall adjoining the front hallway. Photographs of the installation are shown in Figures 2 to 5. The seismic recorder is fitted with a GPS receiver which gives time accuracy to better than one millisecond. The current ground monitor is not accurately timed and is understood to have an internal clock which is reset periodically. If times of similar accuracy could be obtained from both recorders, then observation of arrival times in the building could be correlated with different stages of the blast wave, allowing better indication of the activating vibration.

4 Figure 2: Channel 1 sensor was mounted high on the wall adjoining the hallway. Figure 3: Channel 2 sensor was mounted high on the front wall between the two windows. The timber seen had been placed to prop the ceiling and were temporarily removed for the recording. Figure 4: Channel 3 was as close to the centre of the ceiling as practicable. All accelerometers were mounted using a special wax and masking tape. The mounting materials have been chosen to be the least likely to damage sensitive paint finishes.
