Underwater blasting explosives |
摘要 |
This invention relates to a method of removing underwater obstacles by blasting with a fluid explosure, a device for monitoring the execution of the method from a remote place, a fluid explosive composition especially suitable for the practice of the method, and a detonating device which is very suitable for detonating the fluid explosive. This underwater blasting method comprises the steps of injecting into a blasting hole drilled on an underwater obstacle an inert fluid which is immiscible with water and has a specific gravity greater than water, then injecting a fluid explosive having a specific gravity greater than the inert fluid to replace therewith a part of the inert fluid and thereafter detonating the injected explosive.
