Figures 3.6 to 3.8 show the drawings of the structures. The structures were located on the top
bench keeping the following points in mind:
• The test structures should be located in the direction towards which blasting faces are
progressing.
• The test structures should be away from the blasting site to avoid cracking during
construction period. At the same time it should be close to the blasting site so that the
study could be completed within a period of five to six months.
• The site should be easily approachable for regular monitoring and damage studies.
