Project Report on Stone Mining

The quarry is the type of open pit mine, the rock or minerals are extracted from the quarry. For extracting building materials such as  dimension  stone, construction aggregate,  riprap,  sand  and gravel;  quarries  are generally used. For the  requirements  for large   amounts  of  aggregate  in  those  materials,  they   are collocated  with concrete and asphalt. The process  of  splitting the stones into usable shapes and different sizes for the process of  building  is known as stone quarrying. Stones  from  quarries have  been  used in all types  of stone creations, and  they  are used in the process of constructions ranging from federal offices to  farm  foundations.  In United  States,  stones  quarries  are classified into four major categories, they are boulder quarries, surface  ledge  quarries,  commercial  deep  pit  quarries,   and subterranean quarries. Different strategies are required for each type of quarry to dig out the stones. Quarries  like  commercial deep  bit  quarries just came after the growth of  technology in hoisting stone. The tools used for stone quarrying are, plug  and feather method, and flat wedge method, these two methods  account for  over  95%  of tool marks found on  quarried  stone.  Various methods have been included over the centuries for the purpose  of splitting  stone  into  pieces. They are  classified  into  three types,  they  are; blasting, plug feather method and  flat  wedge method.
