The present invention relates to a rock cutter ship that crushes the underwater rock by impact of dropping a rock cutter weight (100) into the water, comprising: an air injection unit (210) installed in the rock cutter weight (100); and an air supply unit (220) for supplying air to the air injection unit (210). As the air blown from the air injection unit (210) forms air bubbles on the surface of the rock cutter weight (100) when the rock cutter weight (100) falls underwater, the friction resistance in the water of the rock cutter weight (100) is reduced. The provided rock cutter ship of the present invention can increase the crushing efficiency by reducing the underwater frictional resistance of the rock cutter weight.
본 발명은 수중으로 쇄암추(100)를 낙하시켜 충격에 의해 수중 암반을 파쇄하는 쇄암선에 있어서, 상기 쇄암추(100)에 설치된 공기분사부(210); 상기 공기분사부(210)에 대하여 공기를 공급하는 공기공급부(220);를 포함하고, 상기 쇄암추(100)의 수중낙하 시, 상기 공기분사부(210)에서 분사된 공기가 상기 쇄암추(100)의 표면에 기포를 형성함에 따라, 상기 쇄암추(100)의 수중마찰저항이 감소되는 것을 특징으로 하는 쇄암선을 제시함으로써, 쇄암추의 수중마찰저항을 감소시켜 파쇄효율을 증대할 수 있도록 한다.
