Therefore drilling and blasting activities should be designed to ensure that designed parameters produce the desired fragmentation. The Kuz-Ram model is a fragmentation prediction model and is widely used for predicting the fragmentation distribution from blasting in the mining industry.

Iron ore is obtained in the conventional method of open cast or underground mining and conveying the ore to the surface preparation are where it is crushed, washed, and transported to the smelter. Here the ore is put into a blast furnace along with limestone and coke and subjected to hot air blasting and heat which converts the ore to molten iron.

In general, open-pit mining consists of a system to exploit open pits with multiple benches. Operations start with drilling and blasting to remove the plant or sterile overburden and access the orebody, with the rock then being extracted and fragmented at a suitable size for transport to the plant.

Drilling and blasting is the controlled use of explosives and other methods such as gas pressure blasting pyrotechnics, to break rock for excavation. It is practiced most often in mining, quarrying and civil engineering such as dam or road construction.

Underground mining is more complex and more expensive than open-pit mining. Where removing the overburden would be too costly or ineffective to reach the ore, the decision is made to go underground. After open-pit mining is complete, valuable ore can be mined through underground mining methods.

Mining operations like drilling, blasting, hauling, collection, and transportation are the major sources of emissions and air pollution. Coal left in the ground can catch fire, and mine fires are difficult to control, with some burning for decades or even centuries, creating a major source of air pollution.
