See details below
I could not get the correct specifications needed in Opencast mines.
Generally we use 6mm thick steel plate , roll to 1.2 m dia. Make an opening door to open outwards. . This will have a conical top . we surround the structure with gunny bags filled with mud. In case of skid mounted we use 10mm plates against 6 mm. More than specifications , locating is of utmost importance
Factors to be considered for locating a Blasters'Shelter
Blasting shelters are provided in a mine working area for the blaster and his helper to take shelter and to protect them from being hit by flying fragments at the time of blasting.
1. Blaster shelter should be fabricated out of 10 mm thick mild steel plates with stiffeners all around
2. Blaster shelter should be covered with sand bags all around and top, leaving the entrance fully free and without obstructions
3. Blaster shelter should not be used as place to store material and should be completely free
4. Blaster shelter should not be kept on bench edge or places likely to collapse in event of vibration due to blasting
5. Blaster shelter should be placed away from haul road
6. Blaster shelter should be easily approachable with vehicles
7. Door when provided should open outside and designed to remain normally open
8. The opening to shelter should be away from the direction of blast
9. The opening should not be close to face in which case stone could hit and re-bounce into the shelter or any stone getting dislodged from the face in vicinity can fall and roll into the shed
10. In order to enable to see the blasted area after blast, blaster shelter should be located at higher benches. This will also reduce the distance and height of trajectory
11. Blaster shelter should as far as possible located away from the direction of wind to avoid
inhalation of after blast fumes
12. There should be proper arrangement to take the shot firing cable inside without getting damaged
