Abstract

The core of the technology about engineering blasting energy conservation environmental protection is infusing certain volume water to certain position of the blastholes, and then the blastholes are jammed with the blasting mud which is made by special machine. The technology has prominent energy conservation and environmental protection effect compared with the normal engineering blasting. The effect of infusing water to the bottom of the blasthole in practical application was mainly introduced in the paper. The result was analyzed and proved its correct through the stimulant experiment strain tests.
