The drilling pattern used in the main pit mine is the stagger type. Respectively, burden and spacing in iron ore drill are 6 m and 7 m for 251 mm diameter with spacing to burden (S/B) ratio of 1.17. Sub-drilling in iron ore varies from 1.5 m to 2 m with an average of 1.7 m. Drilling pattern in the waste rock is also stagger type.
Drilling and blasting are the two most significant operations in open pit mines that play a crucial role in downstream stages. While previous research has focused on optimizing these operations as two separate parts or merely in a specific parameter, this paper proposes a system dynamic model (SDM) for drilling and blasting operations as …
Iron ore is a rock or mineral from which metallic iron can be extracted economically. It constitutes 5% of the earth's crust. Viable forms of ore contain between 25% and 60% iron. ... Mining iron ore typically …

Abstract. Blasting performance is influenced by mechanical and structural properties of the rock, on one side, and blast design parameters on the other. This paper …
Drilling and blasting is one of the most dangerous mining processes undertaken. Degrees of automation enable drill rigs to do much of their work independently, effectively removing people completely, or lessening workers' exposure to hazards such as dust, noise, vibration and, crucially, explosives. In countries where labour is expensive ...

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 grid in order to cover the major outcrop. The orebody was found to be complex; therefore, the 100 m × 100 m grid was then reduced to a 50 m × 50 m grid in order to obtain sufficient ...

The activities at this truckless mine consist of drilling and blasting, loading and primary crushing. In this study, the calibration of the mine-to-crusher model was based on rock fragmentation from the …
Therefore, the blasted objects are ore rocks, i.e., mainly copper-iron ore containing marble and sand shale. The changes in strain, strain rate effect, and damage of brittle materials are the main factors in the blasting process of ore rocks. ... In the optimization of rock drilling and blasting parameters for high-layered medium-deep …
