Effects of Blasting on Environment - Expert Civil
Environmental Damaged by Vibration. Professional explosive engineer’s design their blast charges so the most of the energy released by the explosion is used up in breaking rock, however, is released as transient stress waves, in other words, ground vibration. This creates cracks in the base of the surrounding rocks near the blast site and travels at different rates through soil rocks and water until the energy of the vibration is dissipated.

It is reasonable to postulate that the size distribution of blasted fragments, and the internal softening of individual fragments by blasting can affect crushing and grinding effectiveness, even though these processes are two to three unit processes downstream from drilling and blasting.
Rock Blasting - Mineral Processing & Metallurgy
In this topic, we will discuss about blasting. Blasting is an operation that engineers resort to in order to break the rock mass, and to facilitate the removal of the overburden material. Blasting is am operation that has safety, stability, and economical viability issues, and it’s a science itself. First of all, blasting requires explosives. Different explosives have different power and ...
THE EFFICIENCY OF BLASTING VERSES CRUSHING AND GRINDING
THE EFFICIENCY OF BLASTING VERSES CRUSHING AND GRINDING by Jack Eloranta ... preconditioned rock and demonstrated changes in Bond work indices of nearly 3 to 1. BOND EQUATION In the early 1950s, Bond proposed an equation for comminution which was based on feed size, product size and a rock property factor. W = 10Wi(1/P^.5 - 1/F^.5) where: W = work input in kw-hr/ton Wi = work index for rock ...
Drilling and blasting - Wikipedia
The standard method for blasting rocks was to drill a hole to a considerable depth and deposit a charge of gunpowder at the further end of the hole and then fill the remainder of the hole with clay or some other soft mineral substance, well rammed, to make it as tight as possible. A wire laid in the hole during this process was then removed and replaced with a train of gunpowder. This train was …

Rock breakage by crushing, blasting, and drilling ...
The principal rock blasting problems involve determination of the proper arrangement of blasting holes, the quantity of the charge, and the sequence of the breakage. An objective of most rock blasting is to produce the maximum rock breakage for the minimum expenditure of energy. A buried explosive charge produces a detonation wave that causes a com- pressive shock wave in the …
