Abstract
This review paper examines extraction methods in the dimension stone industry. Traditional techniques, like thermal shock, hammer and chisel, and plug and feather, were used historically. However, advancements in technology have led to the adoption of mechanized methods. Diamond wire cutting is a highly efficient technique that reduces waste and ensures quality. Challenges like high costs and wire breakage remain. Circular diamond saws and frame sawing are explored as alternative methods. Stone characteristics influence machinery selection and researchers have studied the impact on extraction efficiency. Controlled blasting with explosives shows promise and requires further exploration and optimization.
