The main objective of drilling operations is to create a hole of suitable diameter, depth and direction in rock for explosives to be placed for blasting activities. The drilling of the holes is done normally in a particular pattern which depends on the bench height, the diameter of the hole, the drillingDrilling 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.

Since the 1980s, the JSW team has been specialising in production drilling and blasting, exploration drilling and grade control, successfully completing projects from large scale bulk iron ore and coal mining projects to mid-scale gold and lithium projects. Drawing on this experience and its solutions-focused approach, the company is solving industry challenges – from the development of unique drillingMining - LKAB,Underground mining. Ore is extracted from LKAB's underground mines by means of sub-level caving. This mining method is based on creating cavities in the orebody through drilling and blasting, and allowing the ore to fall down to underlying levels by means of gravity, from where it is transported onwards by train or loader. When the ore is removed, waste rock collapses down and automaticallyAn open pit multistage mine production scheduling,This paper proposes a new multi-resource multi-stage scheduling problem for optimising the open-pit drilling, blasting and excavating operations under equipment capacity constraints.
