Blasting Principles for Open Pit Mining covers both the engineering and the scientific aspects of blasting, with special attention to open pit mining. It serves as both a textbook and a reference for practicing mining, civil, and construction engineers involved in surface rock excavation. Blasting Principles has been divided into two volumes.
1. Introduction. Rock fragmentation distribution influences a range of mining and milling processes including load and haul rates, crushing and grinding performance and ore recovery in beneficiation processes (Michaud et al., 1997).In opencast mining, where blasting is employed for excavation, the overall cost effectiveness of the production operations is compatible with optimization of ...
Divided into two volumes, this accessible work describes the principles involved in hard rock blasting as applied to open pit mines. A large number of examples illustrate the application of the principles. The first volume introduces basic engineering concepts and the building blocks that make up a blast design. The second volume goes into more depth to provide a better understanding of the ...

In normal blasting all holes do not blast at the same time. Bench blasting is normally carried out as short delay blasting. The firing pattern has to be designed so that each blasthole has free breakage. The firing sequence of a chevron pattern can radically alter the drilled burden and spacing into the blasted or effective burden (Be)
