2014-3-14  Drilling in the benches of open pit mining is done for production of iron ore with mechanized drills specific for each mining method. 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.

2021-5-30  The use of water drilling creates smooth, straight holes with minimum deviation, borehole quality, high productivity and little impact on the formation. Whilst using the water powered to scale up ore iron production at LKAB's Kiruna mine, the length of blast holes was increased from 28 to 56 meters.

2015-1-1  Iron ore was won by drilling and blasting ().As mining generally developed, so did drilling techniques and the explosives used. Smith (1990) reported that the Cleveland deposit was associated with a very strong stone roof rock (known as “dogger”) allowing mine drivages to be self-supporting. However, he states that in later years where the mining had progressed to the dip, this ...

2016-6-14  Thabazimbi Iron Ore Mine forms part of the Kumba Resources group. The mine is situated approximately 200km northwest of Johannesburg in the Northern Province. Thabazimbi provides iron ore (2 389 000 tonnes in 2003) for Iscor 1

2018-11-1  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.

2021-6-11  Karara Iron Ore Mine. The Karara mine is located in Western Australia, approximately 225km east of the Geraldton Port. The mine is one of the few magnetite projects developed in Australia. Of the 1.4 billion tons of estimated reserves, 35.5% is expected to be iron ore. The mine is one of the few magnetite projects currently under development in ...
