摘要

To propose a method of collecting an excavation object from a bedrock in form of a shape capable of being used as a material.SOLUTION: A method of manufacturing a material by cutting a part of a bedrock appearing in a direction of drilling in an isotropic hard bedrock as a material includes: a boring process of boring at least a pair of two pores 20, 22 extending in a drilling direction from a drilling surface so as to be placed on a first virtual line extending in a direction orthogonal to the drilling direction; and a pressurizing process of activating pressurizing means in which one of the pair of pores 20, 22 is made into a pressurizing hole 20 by applying the pressurizing means in the hole and the other hole is made into an empty hole 22 having a smaller effective volume than a real volume of the pressurizing hole. The pair of pores 20, 22 are assumed to approach each other to the extent that the following equation 1 is satisfied, where L is a distance from a center of the pressurizing hole 20 among the pair of pores to a hole edge of the empty hole, and D is a diameter of the pressurizing hole 20. The equation 1 is L≤1.5D.SELECTED DRAWING: Figure 1
