きる利点がある。When there are existing facilities or structures such as houses or other existing facilities near the site, the blasting method may cause environmental problems due to vibration and noise during blasting, as well as flying stones, etc.
For safety reasons, the blasting time, number of blasts per blast, and amount of stylus used for one blast are strictly regulated. Normally, one blast will cause an explosion;) F1 C can be blasted in several times. We must do this and dig deeper. Furthermore, in areas where it is completely impossible to use explosives, breakers are sometimes used to crush the rock, but this is inefficient for excavating hard rock layers. In such cases, continuous hole drilling allows the crushing work to be carried out efficiently. In addition, even if there are no restrictions on blasting, if continuous holes are drilled along the excavation pattern such as around the outer periphery of the excavation cross section or around the burn hole, and blasting is performed using this as a free surface, the tensile fracture of the rock can be utilized. Therefore, there are advantages in that the amount of charge is small, the finished surface of the tunnel excavation is good, and the amount of concrete filling by over-drilling can be reduced.
