SURFACE MINING – Mining Engineering Site

20/07/2016  Where minerals occur deep below the surface—where the overburden is thick or the mineral occurs as veins in hard rock— underground mining methods are used to extract the valued material. Open-pit mines are typically enlarged until the mineral reserve is exhausted. Generally open pit mining can be defined as the process of mining any near surface deposit by means of a surface pit

PQ University Lesson 4- Drilling Blasting : Pit Quarry

28/08/2019  Like quarries, mining operations typically have high equipment utilization, drilling up to 80 percent of the working day with DTH technique. The typical blasthole drilled with DTH tools in open pit mines is 5 to 8 in. in diameter. Buffer holes regularly run 5 ½ to 6 ¾ in. Pre-split drilling usually requires hole diameters between 4 ½ and 5 ½ in.

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', ‘pit’, 'open pit' or 'opencast mine'. Within the UK, the largest ...

Blasting Through the Ages: A brief history ... - Pit Quarry

11/06/2020  When the dust settled, everyone looked to see what destruction lay in the wake of the blast. They found rock – not massive rock that would take days or weeks to break, but finely broken pieces of rock that could be brought to the surface for secondary breakage. On Feb. 8, 1627, a new age dawned on the mining industry: the age of blasting.
