Drilling and Blasting Technical Aspects of Mining ...

Drilling. Most blasting in mines involves charging explosives into holes drilled in rock. The entrance or mouth of a drill hole is called the collar and the end is the toe. Drilling is still carried out in some cases, in the ASM sector, by hand, using a hammer and chisel. This is obviously tedious and slow, especially in hard-rock mining conditions. Hand-drilled holes seldom exceed 400mm in length.

Surface Mine Drilling and Blasting Procedure using Surpac

20/06/2017  In surface mining operations, the purpose of drilling into rock is to provide a “blast hole” into which explosives can be loaded (Source: Blast Hole Drilling Module-4). Good drilling practice include carefully monitoring drill-rig operating parameters, taking careful notes of the changes in geology during drilling, and effectively communicating to the blasting crew any unusual conditions encountered during drilling that may affect blasting

The basics about blasting and the requirements explained

07/04/2020  All mining operations require blasting at one stage or another. Blast hole drilling is used in mining where a hole is drilled into the surface rock, packed with explosives and detonated. The aim of this technique is to induce cracks in the inner geology of the surrounding rock, making deeper mining possible. The drilling of blast holes is traditionally used when the mine would like to explore the mineral composition or potential mineral yield of an area that is considered for future mining ...

Blasting Practices in Mining – what you need to know

06/04/2021  What is solid blasting in mining? Solid blasting in mining is a method used for blasting in coal faces. It consists of 12 to 15 shot holes, drilled in a pattern in the coal face equal to the gallery width. Certain explosives and millisecond delay detonators are used for solid blasting. Wedge-cut is the most popular where a set of shot holes get drilled in a wedge pattern with an optional stab hole. The initial free face is created by blasting
