drilling and blasting process

This course will cover the basics of Rock geology related to drilling application, the fundamentals of drilling and blasting process during rock excavation in surface and sub-surface excavation and also it's engineering as well as economic feasibility.

and blasting. In drilling, there is now available advanced use of GPS guided drilling systems that continue to grow and improve precision and effi ciency. Drill depths are accounted for more accurately, making it easier to assign the right amount of explosives in blasting. New GPS-enabled applications have improved strata recognition

Drilling and blasting is both a high risk and core action within the mining industry. Such have to be performed with high precession and accuracy, with heightened levels of health and safety awareness. Drilling and blasting is also time critical due to it being a core process within the mining production cycle.

The buffer blasting at the open pit mines ensures the improvement for the degree of the shattering for the rocks; the control over the burst of the rock mass during the explosion; the independence for the processes of the drilling, blasting, loading, and transportation; the possibility to conduct the selective excavation; the decrease of the

Blasting Area/Zone • The area that may be affected by fly rock, dust, or fumes from an explosion that may cause personal injuries, damages to property, or losses in the process. • The minimum distance for personnel is 500

01/01 · Mining crushed stone generally requires drilling and blasting of solid bedrock (also referred to as ledge or ledge-rock), which breaks the rock into rubble of a size suitable for crushing. Crushed stone and sand and gravel commonly are obtained from dry pits or quarries, but in some settings may be mined from water-filled excavations using dredges mounted on barges, or with draglines.

The Geomining Technological Institute of Spain (ITCE), aware of this progress and of the importance which the breakage process has acquired in mining and civil engineering projects, has ordered the publication of Drilling and Blasting of Rocks.
