Blast hole Drilling is a technique used in mining whereby a hole is drilled into the surface of the rock, packed with explosive material, and detonated. The aim of this technique is to induce cracks in the inner geology of the surrounding rock, in order to facilitate further drilling and associated mining activity.
PDF | This paper studied the current cost trends associated with the drill and blast operations of an open pit gold mine in Ghana and further developed a suitably cost effective drill and blast ...
These operations not only affect the cost of production directly but as well and significantly, the overall operational costs. This research was carried out to find a possible way of optimizing the drilling and blasting operations in an open pit mine of Somair (Société des Mines de l''Air), in the Niger Republic.

Automation has become the catch phrase for mining technology improvements. While mining engineers around the world work toward full automation in openpit mining, they discover the sitespecific variables that require the machines to think and solve problems. Oftentimes those variables become overwhelming when the entire operation is considered.
Open pit mining. Openpit, opencast or open cut mining is a surface mining technique of extracting ore from the earth by digging a large pit. This is done using a wide range of equipment such as Excavators, face shovels, Haul trucks, dozers, graders, wheel loaders and wheel dozers.
I''m looking into trackmounted RC drill rigs that are used for grade control production drilling in open pit mines. Would be interested to hear what rigs (make model) are being used hole diameters and typical depths of drilling.
model to other open pit mines because of differences in rock properties, the prediction methodology applied in this paper can be used in many other predictions of the penetration rates. ! tricone rotary drilling, penetration rate, fuzzy model, blasthole. * University of Belgrade, Faculty of Mining and Geology, Belgrade, Serbia.
Drilling Solutions has released the 2011 edition of Blasthole Drilling in Open Pit second edition blasthole reference book focuses primarily on the rigs, tools, bits and techniques of rotary blasthole drilling, as well as 17 case studies from copper, gold, iron and coal mining in various conditions around the world.
In this paper, a hypothetical open pit copper mine is considered, which needs to produce 30 million tonnes of waste and 25 million tonnes of ore based on its annual planning. This mine works 340 days a year, on which the drilling and blasting operations can be carried out. Thus, the time scale of the dynamic model is set as these operational days.
Surface drill rigs are used for blast hole drilling in construction, quarrying, and openpit mining, covering a hole range between 27229 mm. We offer the widest range of surface drilling equipment on the market, classified into four main product families.
The main conclusion is that manual BH sampling can be fitforpurpose in the studied openpit mine. However, with so many mineral commodities and mining methods in use globally, there is no universal best practice for openpit drill sampling and each case must be evaluated individually.

As rotary blasthole drilling rigs are utilized during the blasting process to create openmining pits, and quarries for mineral and metal extraction, their demand remains constant in the market. These rotary blasthole drilling rigs serve as the most effective machine to initiate the mining activity on a surface.
Nov 28, 2017· "We proved the drill could work in the field and then ran fully autonomous blast hole operations with three Pit Viper 271 rigs. Then it was about a rollout strategy; we decided to adapt a fleet of drills at a time with the automated systems, so as not to disrupt the mine''s daytoday operations.
misfires in open pit mining The unlucky instances in open pit blasting are misfires. The instances of misfire can be all but eliminated if welltrained, careful blasting crews and blasters are employed.
Surface drill rigs are primarily used for blasthole drilling in open pit mining, quarries, and civil engineering projects. The products range from basic pneumatic drill rigs to ultramodern, highefficiency hydraulic drill rigs which offer excellent possibilities to improve the entire mining or quarrying process.
