Abstract

In actual practice, reduction of seismic impact of blasts down to safe level is based on standard technical documentation as well as on recommendations developed by research institutions and specialized agencies. Chiefly, these regulations are concerned with limitation of explosive mass. In the meanwhile, blasting efficiency is governed by strength of rock, various degrees of rock mass fracturing and watering, as well as by different seismic stability of close-spaced facilities, which requires application of different kinds of explosives. This article presents a case-study of seismically safe blasting design and justification for Mikashevichi granite quarry based on the PPV prediction in the basement of guarded objects. The quarry zoning is accomplished by the criterion of allowable explosive mass per one delay interval. The probabilistic PPV prediction method is described. The residential and industrial facilities within the seismic impact zone of blasting in Mikashevichi quarry can experience adverse effect of seismic waves during mining advance, which requires introduction of differentiated limitation of allowable explosive mass per one delay interval. The probabilistic approach to blasting pattern design with regard to theoretical distribution of seismicity coefficients ensures the seismic safety of blasting. The developed chart of seismically safe explosive charges per delay interval ensures integrated safety of all guarded objects at the natural stone quarry, with allowance for closer spaced blasting operations and subsequent mining advance.
