Quarry optimisation good fragmentation less fines

Therefore, optimizing blasting operations at limestone quarries can be defined as a challenge that should be approached step by step on a rational basis. In this paper, a practical case for optimizing blasting operations at a large quarry in southern Spain describes all the evolutions performed in the information, management and technical aspects involved in mine-to-mill

Limestone quarry - MAXAM

Limestone is often produced using opencast mining methods through a multiple bench system, although excavated quarries can also be found via underground mining. Typical operations include drilling and blasting, both designed with a specific fragmentation curve in accordance with the final product to be achieved. After blasting, the fragmented material is loaded and
