The lectures on rock drilling included the topics of drill selection, rotary blast-hole drills, drill bits, and drilling at Sishen Iron Ore Mine. These lectures were given by Messrs G.P. Schivley, C. Marnewick, C.S. Pretorius, and D. R. Brough. Particular mention should be made of Mr George Schivley, of , who came from the
customers of iron ore mines want a specific size range for hematite entering their processes and it has been known that these customers are prepared to pay a 20%premium for 'lump' product. This premium can be achieved with minimal additional costs of production for the iron ore mine and is a very valuable EBIT lever.
Drilling and blasting pattern; Sangan Iron Ore Mine; AHP; TOPSIS; PROMETHEE 1. Introduction Drilling and blasting play a vital role in mining pro-jects.

Abstract. Pre-splitting is a controlled blasting technique with applications in open pit mines. The main objectives of pre-splitting in open pit mining are: preventing/controlling back-break; controlling excessive ground vibrations; and filtering the effects of explosive gases from production blasting.
large excavations in which ring drilling is the main method of rock breakage. Ore dilution consisting of low-grade, waste rock or minefill materials may occur at the stope boundaries. In addition, ore loss due to insufficient breakage can also occur within at the stope boundaries. The methodoffers several advantagesincluding,low cost and

The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.
Chhattisgarh state of India. The mine has very rich deposit of iron ore (hematite). This iron ore series is of Precambrian age (Pichamuthu, 1974). Geo-morphologically the region in and around Bailadila is characterized by relic hill ridges with cliffs and valley topography resulting from the hard-resistant Iron ore deposit. The Bailadila hill

This paper presents an approach to improve overall blasting efficiency in an iron ore mine. The problems existing in the mines were oversize fragmentation, severe backbreak, frequent secondary drilling and blasting operations, sloping bench faces and irregular bench profiles. Thorough analysis of the blasting practices and results was …
Burden movement plays very important role in the bench blasting for the effective utilization of the explosive energy. The optimum burden for a blast face varies with the nature of the strata and explosive quantity & quality. There are various experimental and empirical approaches for the estimation of optimum burden. However, there is a need for …
