  • What is Quarrying?

    The materials produces by quarrying are essential to our everyday lives, providing the construction materials to build roads and buildings, delivering vital minerals to agriculture and supporting the generation of electricity – to name just a few uses It is tempting to see a quarry as an undesirable ‘hole in the ground’ but we need our quarrying industry to supply us with vitalQuarries are normally utilized for extracting building materials, like dimension stone Quarries are normally shallower than other kinds of openpit mines Quarries are also at times used as filming locations In other words a quarry is a big manmade hole in the ground from where minerals or rock are taken out Quarries are made when big deposits of commercially helpful minerals or rock areQuarry Mining, OpenPit Mining, Strip Mining, Mining
