Maximize mining exploitation efficiency of the quarry: a case study

Nowadays, the dimension stone industry performs a crucial role in world economy. Accordingly, quarries’ importance grows due to their different applications various construction, building, and decorative industries. Some issues threaten this provide financial risk that should be taken into account make smallest possible for investment. The presence of discontinuities rock mass has key function as far it concerns overall quality situ blocks. It impacts feasibility quarries mine exploitation efficiency. Therefore, is recommended survey blocks estimate average geometry block, including shape size, before mining benches maximize efficiency minimize waste ore production. This investigation aims limestone quarry located Josheghan, Iran, determine calculate blocks’ suitable an extraction’s direction active benches. For purpose, scanline method was applied seven 3DEC software used indicate model all concluded benches’ cutting line 13.14 degree with main’s direction. result study proved by changing extraction benches, unnecessary production would decrease. rate will increase about 1.13% compared current direction, which makes degrees Currently, bench recorded minimum rate, 97.60; applying new predicted achieve 99.83 rate. Consequently, improving considerably.
