Question 1

By line go through the 6 step problem solving format for Hasty Crater Charge ?

Answer 1

1) How wide
2) 5ft deep (Times) 10 lbs. explosive per hole = 50
3) N/A
4) 50 divided by Package weight
5) (width) minus 16, divide by 5, plus 1 (round) = number of holes
6) 50 lbs. per hole (times) number of holes = Total number of packages

Question 2

By line go through the 6 step problem solving format for Deliberate Crater Charge ?

Answer 2

1) How wide
2) 7 foot hole: 80 lbs. 5 foot holes: 40 lbs.
3) N/A
4) 80 & 40 divided by Package weight
5) (width) minus 16, divide by 5, plus 1 (round) = total number of holes.
6) 7 ft./5 ft. totals per hole (times) number of holes = Total number of packages.

Question 3

By line go through the 6 step problem solving format for Relieved Face Crater Charge ?

Answer 3

1) How wide
2) Friendly: 40 lbs. Enemy: 30 lbs.
3) N/A
4) 40 & 30 divided by Package weight
5) (width) minus 10, divide by 7, plus 1 (round) = number Friendly of holes.
6) Friendly/Enemy totals per hole (times) number of holes = Total number of packages.

Question 4

How do you figure the number of 7 foot and 5 foot boreholes needed for a deliberate crater ?

Answer 4

• Where there is an even number of boreholes needed there will be two more 7 foot boreholes then 5 foot.
• Odd numbers result in a difference of one.

Question 5

What are the 3 type of Boulder removal methods ?

Answer 5

• Mudcapping
• Snake hole method
• Block hole method
