Drillers in this unit group operate mobile drilling machines to bore blast holes in openpit mines and quarries and to bore holes for blasting and for building foundations at construction sites. Blasters in this unit group fill blast holes with explosives and detonate explosives to dislodge coal, ore and rock or to demolish structures. They are employed by mining, quarrying and construction ...
· Quarrying of stones is the art of extracting stones from the rock beds. The place from which the stones are obtained (by digging or blasting) is known as 'Quarry'. Quarrying differs from mining in which various operations are carried out for exploring minerals, such as coal, quartzite, etc. from a mine under the ground. 2.

· 12 This illustration shows the schematic view of a quarry operation. 13. 13 This diagram shows the extension of an ore body to be mined after removing the over burden/ waste lying both sides of it. The bench slope is about 45 to 72 degrees. Systematic blasting is necessary to mine this ore body. 14. 14 What is blasting?
What is Quarrying? Quarrying is the process of removing rock, sand, gravel or other minerals from the ground in order to use them to produce materials for construction or other uses. So, a quarry is any such working on the surface of the earth where minerals are extracted. Quarries are also known by other names around the world: 'surface mine ...
blasting cap when unconfined; and Blasting agent (BA) = a mixture consisting of a fuel and oxidizer, intended for blasting but otherwise not an explosive (cannot be detonated with a No. 8 blasting cap). The makeup of a standardtest No. 8 cap, of the sort used as a detonator in the blasting industry, is shown to the right.
Opencast mining or quarrying of minerals is easier than mining by underground methods. During quarrying the alluvium and rocks below which the minerals lie, are removed and dumped, in the initial stages, in a place which is not required in future for quarrying, residential or other purposes.

If it were deemed necessary to be able to maintain quarry faces throughout the life of the quarry, this would mean that extremely wide benches would have to be designed in to allow plant access. It is suggested that this is impractical and would have a profound effect on the design of rock faces and quarry slopes, the operating costs and the profitability of the quarry, and make most quarries ...
