- Buffer Blasting Method
Controlled blasting is a specialized method that aims to minimize the undesirable effects of blasting, such as ground vibration, air overpressure, and fly rock. Techniques included in Controlled blasting are Line drilling, Smooth (Contour or Perimeter) blasting, Pre-splitting, Buffer blasting, and Post blasting.

Line drilling, trim blasting, buffer blasting, smooth wall blasting, air decking, and presplitting are the six controlled blasting methods that have been developed. In the mining, construction, and tunnelling industries, there are a number of controlled blasting methods that are rarely used.

Buffer blasting is a term I used for a similar scenario as Smoothwalling except an additional buffer row is added between the production blast and the perimeter holes. The buffer row is lightly loaded (lower density explosive or slightly decoupled charges) compared to the production holes.

One approach was to use a shallow throw (cast) blast followed by a separate post-strip blast underneath. Another method was the introduction of the practice known as "baby decking" with the addition of a large buffer of material in front of the coal.

Buffer Blasting refers to a designated section of rock between a slope or wall to be formed by line drilling or presplitting during excavation and the production blast. The explosives in the buffer blasthole and the burden in the buffer zone are reduced to prevent damage to the final rock …

These techniques have a common objective to minimise fracturing and loosening of the rock beyond the excavation line, and include line drilling, pre-splitting, buffer blasting and trim blasting. In final wall blasting, the degree of confinement of the explosives energy adjacent to the slope plays a key role in the amount of wall damage produced.
