Evaluation of blast efficiency in aggregate quarries: facts and ...
2021.3.13 The stone aggregates are typically obtained by drilling, blasting, and crushing. Primarily, in-situ rocks are drilled, blasted, loaded, and hauled to the crushing plant for further processes. The results of blasting have been proved to affect every other downstream process leading to the production of various aggregate sizes (Workman and ...

2019.3.1 The aggregates from the rock mass are extracted by drilling and blasting. The blasting aims to detach the material from the bedrock to a size that is suitable for loading and hauling and transportation on a conveyor belt. Crushers also have specifications for the maximum block size.

2013.4.21 This paper examines the role blasting plays in optimum crushing and grinding with the emphasis on energy reduction. The role of different blasting energy input on fragmentation is studied, and related to needs at the plant. The effect of different feed sizes on energy consumption in crushing and grinding is studied.

2012.1.1 Mining crushed stone generally requires drilling and blasting of solid bedrock (also referred to as ledge or ledge-rock), which breaks the rock into rubble of a size suitable for crushing. Crushed stone and sand and gravel commonly are obtained from dry pits or quarries, but in some settings may be mined from water-filled excavations using ...

Compared to other methods, conventional drilling and blasting provide more realistic solutions to the two most important mining issues, i.e., mining cost and production efficiency [ 2, 3 ]. However, there are certain direct negative impacts that can arise when using these conventional methods for rock breakage.
