Typical Blasting Methods for Structural Engineering Operations

Blasting is the process of cracking rock material by using a small amount of explosive substance so that the rock is destroyed into several pieces. In the past, black powder and dynamite were used for the explosive process. Blast design and execution are important for successful rock removal operations.

Blasting OSMRE

Apr 24, 2017 View an extensive list of blasting resources (ARblast) Blasting is an integral part of surface mining operations. To uncover coal reserves, the rocks overlying the coal are broken with explosives and excavated with various types of large earth-moving equipment. Without blasting, a vital part of the nation's energy reserve would be inaccessible.

1. Introduction The optimization process aims to minimize the unit cost (€/m3) of the operations that integrate the primary blast, secondary and crushing rock, taking into account pre-established criteria to obtain a lower global cost per m3. In this way, a pseudo-optimal geometry of the blast was generated through the resolution of the model by the Solver Excel tool.
