Pre-split blasting is a controlled blasting technique used in mining and construction to create a precise fracture plane in rock before the main blast, minimising overbreak and controlling the final wall shape. This method involves drilling closely spaced, parallel holes along the desired final rock face and lightly charging them to produce a clean, stable split in the rock.

The pre-splitting method of blasting is a controlled technique used in mining and construction to create a clear, defined break in rock, reducing the risk of overbreak and minimizing damage to the surrounding area. This method involves drilling a series of closely spaced, aligned holes along the desired final contour or boundary and then loading them with explosives. The primary goal is to induce fractures along these pre-drilled lines before the main blast occurs. This controlled fracturing all
