A method for preparing a bedrock crushing agent is provided to produce the bedrock crushing agent which gasifies and expands a component using an exothermic reaction of a thermit agent and has no reaction waiting time. A method for preparing a bedrock crushing agent using an electric shock includes the steps of: drying and mixing 30-45% of aluminum powder, 5-10% of copper oxide powder, and 50-60% of polyoxymethylene powder; and molding the mixture into particles having a particle size of 0.2-1.0 mm using an acrylic binder. A weight ratio of the copper oxide to aluminum is 5-20w%. The polyoxymethylene is used in an amount of 10-60wt% based on the total weight of aluminum and copper oxide. |
