Controlling the Adverse Effects of Blasting

control and minimize the adverse effects . Blasting Impacts on Structures . Ground vibrations propagate away from a blast site as Rayleigh (or surface) waves. These waves form a disturbance in the ground that displaces particles of soil or rock as they pass by. Particle motions are quite complicated. At the ground surface (free boundary), measured particle motions have the greatest ...

Effects of water deck on rock blasting performance ...

In this study, a new blasting concept – water deck blasting (WDB) is introduced which sealed the water at the blasthole bottom to prevent adverse effects of water as well as maximise the beneficial effect of water on rock breakage performances. A field experiment was conducted in a quarry, bench blasting including twenty-three watery holes among 139 blastholes. Promising results were ...

Denser rocks such as basalt require smaller ratios (higher powder factors). Lighter materials such as some sandstone or bituminous coal can be blasted with higher ratios (lower powder factors). The hardness or brittleness of rock can have a significant effect on blasting results. If soft rock is slightly under-blasted, the rock probably will still be excavatable. If soft rock is slightly ...
