Methods of quarrying include: a) Digging – This method is used when the quarry consists of small & soft pieces of stones. b) Heating – This method is used when the natural rock bed is horizontal and small in thickness. c) Wedging –This method is used when the hard rock consists of natural fissure.
What is quarrying and explain any one method in detail?
Quarrying of stones is the art of extracting stones from the rock beds. The place from which the stones are obtained (by digging or blasting) is known as ‘Quarry’. Quarrying differs from mining in which various operations are carried out for exploring minerals, such as coal, quartzite, etc.
