    Optimization of blasting design in open pit limestone

    Jun 02, 2020 Blasting is the process, where explosives are used to fragment the rock mass, so that loading equipment can handle the fragmented rocks. The main objective of blasting is to fragment and displace the rock mass (Mehrdanesh et al. 2018).Nevertheless, in these operations, a huge amount of explosive energy is not used in actual fragmentation and creates number of blast nuisances, such as blast

    Chapter 8 BLAST DESIGN - NPS

    The economic analysis of the use of explosives is an important part of blasting operations in mining and construction. Explosives are energy, and the efficient use of this energy is a major factor in keeping rock blasting costs under control. High-energy explosives enhance fragmentation, which ultimately produces a positive effect on production

    The more complicated the limestone structure, the more sampling and testing required to ensure the delivery of quality limestone to the process. In these conditions, the number of core holes will have to increase to define the areas of quality limestone and the geologic structures, and to determine the “mineability” of the deposit
