Pre-splitting blasting technique is a method employed in rock excavation to create a fracture plane ahead of the main blasting zone. It involves drilling a line of closely spaced holes along the desired contour, typically using smaller diameter drill bits. These holes are then charged with explosives, but the detonation sequence is carefully controlled to ensure that the fractures propagate smoothly and evenly along the designated plane. Pre-splitting helps in achieving a smooth excavation face,

💣 Pre-splitting blasting 💣 Achieving a solid backbreak is essential for preserving wall stability and maximising blasting efficiency in mining operations. 💣 To establish a controlled fracture plane, pre-splitting entails drilling closely spaced holes along the intended final wall line, mildly charging them, then detonating them prior to the main blast. 💣 By guaranteeing a precise and well-managed cut, this method lowers overbreak, improves wall stability, and lessens vibrations from the grou

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
