Safe operation of mining-and-transport system under impact of seismic shot waves

Authors: Vasilets V. V., Afanasev P. I., Pavlovich A. A.

In the Russian Federation, the surface mining method enjoys active and extensive development. However, there are difficulties which slow down production and lead to appreciation of operating costs. The increase in the mining rate and in the depth of open pit mines builds up the process transportation expenses and raises the current stripping ratio. One of the possible solutions is transition from rock haulage by trucks to conveying. The transition from the cyclic method to the cyclic-and-continuous technology allows high-production equipment, elevated availability factor and low operating costs. These systems are arranged on the spoil bank and require the seismic safety design. The concern of the pitwall stability with operating cyclic-and-continuous technology conveyor under the seismic shot impact is discussed. The basic normative and scientific procedures of drilling and blasting parameters to ensure safe seismic shots are analyzed, and the variant of the seismic shot impact estimate in different geological conditions is proposed. An alternative method to estimate allowable peak particle velocities in sedimentary rocks is substantiated. The practical guidance on safe blasting nearby a mine transportation system is presented.

Keywords: Seismic shot waves, seismic safety, cyclic-and-continuous technology, pitwall stability.
