Determining Acceptable Explosive Charge Mass Under Different Geological Conditions / Problematyka Wyznaczania Dopuszczalnych Ładunków Mw W Zróżnicowanych Warunkach Geologicznych

Abstract

PROBLEMATYKA WYZNACZANIA DOPUSZCZALNYCH ŁADUNKÓW MW W ZRÓŻNICOWANYCH WARUNKACH GEOLOGICZNYCHThis article presents a procedure for determining the safety of explosive charges for their surrounding environment, using a limestone mine as a case study. Varied geological structures, as well as other constructions in the surrounding area of a mine, sometimes necessitate the use of two or more ground vibration propagation equations, and thus a variety of explosive charges, depending on the area of rock blasting. This is a crucial issue for the contractor, as it is important to blast the rock as few times as possible, while using the maximum amount of explosive charge for each blast.

“…Such research has covered the geological structure of blasting sites and the ground which propagates vibrations, blasting techniques, estimated and actual vibration levels, interactions between buildings and the ground, and monitoring and recording of the impact on civil structures. The above-mentioned issues need to be explored to protect the environment against excessive vibrations (Pyra et al, 2015).…”
