REVIEW NUMBER 3 ANSWERS TO QUESTIONS Q1. THROUGH Q9.
The mine case contains or carries all other components.
The explosive components of a mine include the main charge, booster, initiating
system, and auxiliary explosive devices.
Between 160 and 1,300 pounds of explosives are used in air-laid mines.
After a mine is planted, a clock-delay mechanism prevents the mine from firing
until it has been submerged for a predetermined time.
The range of the delay time in planted air-laid mines is from 8 minutes to 10 days.
Influence-actuated firing mechanisms include acoustic, pressure, and magnetic.
Acoustic mines are detonated by the sound waves generated by nearby ships’
rotating screws.
A decrease in the water pressure immediately surrounding the mine actuates the
pressure mine.
A change in the earth's magnetic field actuates the magnetic type of mine.
