Aiming at the main ice-breaking problem faced by Ningxia-Inner Mongolia reach of the Yellow River，the characteristics and types of ice flood disaster of this reach have been studied firstly in this paper。Secondly，the advantages and disadvantages of the different ice-breaking technology have been analyzed comparatively。Based on this，through analyzing the characteristics and application conditions of the new research ice blasting equipment and comparing different position，different position ice breaking equipment，operation timing and implementation plan，a variety of the blasting technical schemes of the emergency ice breaking that were suitable for different ice，ice flood，ice dam formation and sectional characteristics have been put forward。Therefore，it provided technical support for enhancing the measures and emergency response capacity of the control and reduction of ice flood disaster for the Ningxia-Inner Mongolia reach of the Yellow River through the ice flood period safely。
