3 The method used for quarrying of stones depends upon on the types of stones its intended use and the type of its geological formation For Example, when the rock formation consists of horizontal layers at shallow depth, we may be able to easily quarry them in layers In other Words, If the stone is one whole crystalline mass, we have quarryppt 1 By Argaw Tarekegn 1 ; 2 By Argaw Tarekegn 2 ; 3 Quarry is a type of open pit mine from which rock or minerals are extracted Quarries are generally used for extracting construction materials, such as dimension stone, rubble stone, fine and coarse aggregates etc Quarries are usually shallower than other types of openpit minesquarryppt SlideShare

8Extraction Method and Processing: Quarrying and Mining: The open part of the natural rock from which useful stone is obtained is known as quarry Dimension stone quarried or mined without use of blasting techniques, which could have serious detrimental effects on the structure of the softer stone varieties The quarry face initially Quarrying of Stones using Machines: Channeling Method: • In this method of quarrying involves the use of big machines called Channelizers which have reciprocating cutting tools and are power driven • When single large blocks of costly stones like marbles and limestones are required, this method is most suitableIntroduction and classification of rocks PPT SlideShare
(PDF) ROCK BLASTING FOR MINING ResearchGate
With proper understanding of the rocks and blasting methods, the mining work can be done effectively The basic objective of this report is to highlight the principles and practices adopted inSolution mining is used to recover deep deposits that would be uneconomical using underground methods, but only if the ore can be easily dissolved by a solvent In this method, holes are drilled from the surface into the deposit A solvent is pumped down one hole, and the resulting solution with the dissolved mineral is pumped out another hole431: Surface Mining Methods GEOG 000 John A Dutton e
