Question:
Blasting requires certain steps in order to be effective. Outline those steps from designation of the blast location to setting up for the next blast.
Roadheaders can be used for tunnel excavation in a rock medium. Describe the operations of a typical roadheader operation.
Focus
This module shows two methods of excavation that cover specific ways of tunnel and shaft excavation:
Blasting is a method that is used at sometime in a rock tunnel. Students should consider the methods and procedures for blasting and the steps in involved in a blast sequence including blast cleanup.
A roadheader on the other hand is a method which is selected based on the shape of the tunnel, the compressive strength of the rock and factors associated with money. A roadheader has a much smaller upfront cost, but is slower to preform an excavation. Students should understand that equipment like this is available and the conditions for its use.
Deliverables
Prepare a 3 paragraph discussion for each of the blasting and roadheader methods. Describe the procedure used and risk that must be considered
