An approach to improve blasting efficiency in an iron ore mine

Read this article. This paper presents an approach to improve overall blasting efficiency in an iron ore mine. The problems existing in the mines were oversize A block model is created from information obtained from exploration drilling. For the iron ore mine, the initial exploration drilling was done on a 100 m × 100 m Mine Planning and Optimisation Techniques Applied in an Iron Ore Mine

Blastability and Ore Grade Assessment from Drill Monitoring

Mining consists of several unit operations linked to each other, and the performance of the initial stages (drilling, charging and blasting) pre-conditions the downstream unit operations in the production cycle (Ghosh 2017).For an efficient blasting, it is essential to have a well-defined characterization of the rock mass; automatization in to improve the fragmentation of the ore is by changing the drilling-and-blasting design parameters. It of course increases the mining costs, but at the same time decreases the costs of the following processes, which are normally significantly higher. Therefore, authors of this article propose a new way of optimization ofOptimization of the drilling-and-blasting process to

Prediction of Dust Emission Due to Open Pit Mine

Drilling and blasting operations have been used in civil and mining projects due to lower operational costs and higher efficiencies. During the blasting operation, a huge volume of energy is released, In China, mining blasting vibration has seriously threatened the safety and stability of high and steep rock slopes. In this paper, taking the east mining area of Jianshan Phosphorus Mine as the research background, combined with field survey, field blasting test, numerical simulation and theoretical analysis, we systematically studied the adjacent high-steep Study on Blasting Technology for Open-Pit Layering of Complex Mine

Blast-Induced Rock Fragmentation in Wet Holes SpringerLink

In the present research, rock fragmentation in dry and wet blast holes charged with wetness-sensitive explosives (i.e., ANFO) and water resistance explosives (i.e., the emulsion) was modeled and analyzed. For this purpose, rock fragmentation conditions at the mine were studied under three scenarios: Scenario 1: blasting a dry Ring drilling and blasting is done from a series of sub level drill drifts developed in the ore body. The drill pattern is designed to cover off the ex tent of the ore in the stope.(PDF) ROCK BLASTING FOR MINING ResearchGate

Aryafar et al. [11] determined the optimal drilling and blasting pattern in the open-pit iron mine by first using AHP method under a fuzzy environment to define the weight of criteria and thenThe wide holes in the ground created by drilling, blasting, and ore removal are referred to as open pits. Areas for open pit mining are selected using the mining plan. Fig 2 Typical surface iron ore mine.

In an operating open-pit mine, improving the productivity of heavy mining equipment (HME) enables the unit cost of production to be reduced. To optimize HME productivity, the Kolomela open-pit iron ore mine transitioned to an enhanced short-term mine planning (STMP) processImproving productivity at an open-pit mine through

Iron Ore Processing, General SpringerLink

Iron ore handling, which may account for 20–50% of the total delivered cost of raw materials, covers the processes of transportation, storage, feeding, and washing of the ore en route to or during its various stages of treatment in the mill.. Since the physical state of iron ores in situ may range from friable, or even sandy materials, to monolithic The extraction stages of open-pit metal mining ores include drilling, blasting, loading, and haulage. The appropriate implementation of this process has a significant impact on production costs, the quality of the product, and the production rate. Jahani, M.; Taji, M.

GEO ENVIRONMENTAL IMPACT & ITS MANAGEMENT

The major source of dust production in the mine is drilling, blasting and vehicle movement. Drilling is done by wet drilling method by providing water injection system and also dusts extractors which are fitted at the collar level to collect the dust. Continuous work on improving the powder factor is down to produce minimum quantity of dust.Drill and Blast Technician. Nov 2020 Sep 20221 year 11 months.
