  • Quarry Wikipedia

    Apr 01, 2003· Stone quarry is an outdated term for mining construction rocks (limestone, marble, granite, sandstone, etc.). There are open types (called quarries, or open-pit mines) and closed types (mines and caves). For thousands of years, only hand tools have been used in quarries. In the 18th century, the use of drilling and blasting operations was mastered.Drilling and Blasting Technical Aspects of Mining,Drilling with drifters and electrohydraulic rigs is called longhole drilling. In small-scale surface mining including small quarries, jackhammers are in common use but in larger quarries and open pits, various types of mechanised rigs are employed. They drill holes of Open-pit Mining Mining North Works,The open-pit mining cycle includes drilling ore and waste rock, loading drill holes with explosives, blasting, ore loading and hauling to stockpiles for processing, waste rock loading and hauling to the waste rock storage pile. Occasionally, drilling and blasting ore is not required and can simply be removed by what is known as free digging.
