    摘要： This invention relates to a method of removing underwater obstacles by blasting with a fluid explosure. 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.

    摘要： A lithotriptor is disclosed, which comprises an outer slender tube having an outside diameter small enough to be inserted into the organ growing a stone therein and an inner member disposed inside the outer slender tube. The inner member or the outer slender member incorporates therein an explosive layer or a gas-generating layer, ignition means for igniting the explosive layer or the gas-generating layer, and a closing member for preventing rearward advance of the gas evolved during the explosion of the explosive layer or the gas-generating layer. By the blasting of the explosive layer or the gas-generating layer, the outer slender tube or the inner member is caused to collide with the stone and crush it.

    摘要： This invention relates to a method of removing underwater obstacles by bling 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.The monitoring device is provided with a means for electrically detecting the level of the fluid explosive injected into the blasting hole. The fluid explosive composition contains as the explosive ingredient urea perchlorate. The detonating device is a float provided with a detonator which can act upon the fluid explosive from a remote place.
