Monitoring of Earthquake Loads from Blasting in the Shakhtau Open Pit Mine

Resumo

The monitoring results on earthquake loads from blasting in the Shakhtau open-pit mine in 2016–2017 are presented. The integrated model of influence exerted by the parameters of drilling-and-blasting and the environment on the surface earthquake loading is developed, which allows high-precision prediction of the seismic effect value at any point of a study area. The estimates of the short-blasting initiation errors are given. It is concluded on the promising nature of continuous blasting monitoring in difficult geotechnical conditions when reliability of standard seismic effect valuation procedures is insufficient.
