1. Introduction. Mining activity is mostly represented by these four main operations: drilling, blasting, loading and hauling. For a proper mine planning and design, all of these operations need to be carefully planned in such a manner that can prevent extra loads such as operating costs, environmental footprints, etc. Amongst these operations, drilling and …
We offer rock drilling machines and other equipment for many different applications. For example; oil and gas, construction drilling, quarrying, surface mining, underground mining, exploration drilling and dimension stone industry applications. "Smart mining" – safer, leaner and greener operations with semi- or fully automated processes
Mining - Blasthole Stoping, Ore Extraction, Drilling: When the dip of a deposit is steep (greater than about 55°), ore and waste strong, ore boundaries regular, and the deposit relatively thick, a system called blasthole stoping is used. A drift is driven along the bottom of the ore body, and this is eventually enlarged into the shape of a trough. At the end of the trough, a …
Achieving high productivity from large capital equipment items such as draglines depends on consistent fragmentation and muckpile presentation to reduce rehandle and unnecessary movements. By careful planning and blast design, …

Component Function and purpose Main structure; Drill rig: Frame, rotation and auxiliary operating system of the raise boring machine: Provide thrust, tension and torque for rock breaking; sustain reactive tension and torque in the drilling process; transmit the reaction force to the rig base; achieve the purpose of dismantle or connect the drill string
Borehole drilling is intended to probe the geological conditions in deep stratums. First, rock (ore) core, rock debris, liquid samples (e.g., petroleum, water, geothermal water, mineralized water, and crystal water), and gaseous samples (natural gas, carbon dioxide, hydrogen, and helium) are extracted from the mid segment of the borehole, and are used for …
Drilling consists of sinking a drill string into the ground while injecting a special mud. This allows fragments of rock and samples of gas to be brought back to the surface. Boreholes have to be drilled at several locations to delineate the potential deposit.
Once the ore is crushed to the appropriate size, it enters the grinding stage, where the manganese ore is refined into a fine powder using specialized equipment such as ball mills or vertical roller mills. To achieve this, various crushing equipment such as jaw crushers, cone crushers, and ball mills are commonly used to crush and grind the ore.
Image Credit: Adwo/Shutterstock. Reverse circulation (RC) drilling has become standard practice in most mines across the world. First developed in Australia in the 1970s, the drilling technique was originally conceived as a solution to the drilling difficulties encountered when using open hole techniques in soft iron ore and mineral sands.
Vast amounts of key resources such as iron ore, copper ore, precious metals, and coal are extracted globally every year to satisfy commercial demand. ... Moreover, mines are highly dynamic workspaces, with multiple vehicles and …

The high cost of drilling has a serious impact on mining operations requiring strategies which use advanced technologies and techniques that closely monitor the drilling operations to reduce costs ...
The portion of the ore body to be removed is first drilled in a specific pattern. The drilling is conducted with large mechanized drilling rigs. The chief 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.
Iron ore mining operations, particularly those involving quarrying, present a unique set of challenges and risks. From the use of specialised equipment like geological tools, drilling rigs, and blasting equipment, to the potential for significant environmental and safety hazards, the complexities of the industry are vast.
Newcrest test drill and blast technology in New South Wales.
