Seismic source mechanisms for quarry blasts: modelling
IntroductionObservationsModellingConclusionsDescription of quarry blastsThree blasts were recorded from the Chemical Lime Quarry, ‘Chemlime’, in Central Texas summarized in Table 1, illustrated in Fig. 1 and previously described in Bonner et al. (1996). Each shot consisted of between 28 and 42 holes of approximately 165 lb each (W= 76 kg) of ANFO sDataThe objective of our study was to compare local (∼10 km) recordings of short-period surface waves with numerical modelling results from different quarry blast sources. The short-period surface waves excited by a surface source at this distance in simple geological structures are th在academic.oup上查看更多信息作者: Keith L. McLaughlin, Jessie L. Bonner, Terrance Barker

Seismic source mechanisms for quarry blasts: modelling
2004年1月1日 A theoretical understanding of the mechanisms by which quarry blasts excite seismic waves is useful in understanding how quarry blast discriminants may be transported from one region to another.
