摘要： The present invention relates to a crushing method using large boreholes in an underwater rock in which plural large boreholes are drilled on the rock in a predetermined space, the drilled boreholes form plural free surfaces, and the large drop hammer gives a blow to the free surface, thus enhancing the crushing effect.The crushing method is comprised of the following processes: plural large boreholes, of which each size is 100˜300 mmφ, are arranged on the rock to be crushed, and are drilled in a depth of 1˜10 m, and the free surface is reserved before the drop hammer work; a middle point between the adjoining large boreholes is set as target point; the drop hammer is lift above a position perpendicular to the target point, and is free-fallen to give a blow to the rock to be crushed; and the above processes are repeatedly operated.

摘要： The present invention relates to an underwater rock boring apparatus having differential global positioning system receiver and boring method thereof, new boring technology—a satellite navigation device orients the accurate position of a target—is brought to the underwater boring technology.A differential global positioning system (DGPS) receiver is provided at the body of a boring machine that is installed at the central opening of a self elevation platform (SEP) barge, the location of the boring machine is set to concentricity of the target boring position, and the position of the hull can be controlled without any movement of the boring machine. Then, the barge quickly moves to the next target boring location owing to the operation of a hull moving means so that the construction efficiency of the boring work can be enhanced.
