The terms open-pit and opencast refer to the type of surface mining which results in a depression or deep funnel-shaped pit surrounded by sloped or stepped walls At these types of surface mines a material s hardness ultimately determines how it will be extracted...
SURFACE MINING METHODS A surface mine is an open-air excavation for removing minerals Surface mining can be employed to extract metallic or nonmetallic mineral from any near-surface deposit in any rock type Near-surface generally implies deposit less than 500 ft the size of the deposit may range from a few tons to more than 100 million tons...
Blast hole Drilling is a technique used in mining whereby a hole is drilled into the surface of the rock packed with explosive material and detonated The aim of this technique is to induce cracks in the inner geology of the surrounding rock in order to facilitate further drilling and associated mining activity...
Jun 19 2017 0183 32 The degree and the efficiency through which drilling and blasting is done actually determines the quality of the broken material for eventual downstream processing In surface mining operations the purpose of drilling into rock is to provide a blast hole into which explosives can be loaded Source Blast Hole Drilling Module-4...
