The slope stability of the Itakpe Iron Ore Mine has been carried out using computer software, ROCKPACK III. One hundred and twenty three dip and dip direction values were obtained using compass clinometer. The Itakpe Iron Ore Mine was divided into four benches 241 - 258 m, 263 - 275 m, 276 - 286 m and 308 - 312 m. Joints along the discontinuities were mapped.
Height amp Width of benches will be kept as 9 m and 20 m respectively. The area is marked by undulating hills with altitude varying from 508.18 m to 637.23 m.... Roida-I iron ore mine contains 70 iron ore of 60 Fe content which is suitable for blast furnace and steel melting shop.

Meghahatuburu Iron Ore Mine MIOM, located in the eastern part of India. At KIOM experiment site, surface RL is 827 m. It has 3 benches with first and second bench 9 m high and the bottom third bench is 8 m high. The pit bottom RL is 801 m.
The geological profile perpendicular on the west wall of Chador-malu iron ore mine. In this study, in order to save time and costs, three blocks No.
The purpose of drilling is to make holes that we then fill with blasting agent. As a rule, we drill to a depth of 13 14.5m, since we have chosen to have a bench height of 12 m in our mine. We normally drill 150 300 holes, load 50-100 tonnes of blasting agent and often release 300,000-1,000,000 tonnes of rockore with every blast.
the Jalal-Abad iron mine based on nearly fifty studied blasts. 2. Jalal-Abad iron ore mine The Jalal-Abad iron mine situated approximately 36 km NW of Zarand, with 200 Mt iron ore resources with an average grade of 38.5 is one of the important iron deposits in Kerman Province, SE Iran 5, 6.
drilling and blasting operation will be carried out at hard laminated iron ore zone for loosening. These loosened iron ore then excavated and loaded to the dumper for processing. The processed ore will be used in companys own steel plant. Proposed bench height in the quarry area is 10 m with 20 m working width.
