Method for blasting the vast hole using blast pressure effusion inhibition device

摘要

The present invention relates to an innovative blast pressure eruption suppressing device which is capable of innovatively reducing generation of dust, noise, and vibration, and reducing scattering of a rock crushed by blasting while maximizing blasting force by blocking an entrance of an empty hole when a long hole is blasted to explode by making a long hole, and a high efficiency method for blasting a long hole using the same. According to the present invention, while an explosive and a tamping material are alternately repeated and loaded, a blast pressure eruption suppressing device is tamped after the blast pressure eruption suppressing device is installed in an entrance of an empty hole. Therefore, an excessive outflow of explosion pressure gas to an outside can be prevented in a blasting work, and scattering of a crushed rock can be prevented, and generation of dust, noise, and vibration can be reduced. Blasting efficiency can be improved since a second free surface is effectively formed in an inside of an empty hole.
