Abstract:
     The granulated emulsion explosive for rocks is a kind of explosive prepared as follows. The emulsion explosive and anfo explosive are prepared respectively according to the technology and formulae prescribed in this invention. Then the emulsion explosive and anfo explosive are mixed at a ratio of 10-50%: 50-40% to form the granulated emulsion explosive for rocks. In the production of this explosive, addition of sulfur powder is not required, and no foaming process is needed; therefore, the production cost is reduced. This explosive is water-resistant and sensitive to detonation induced directly by the primer with good explosion performance. This explosive, which can be blown out by a pneumatic charger and stuck well into the drill hole with small back-flow of explosive, is suit-able for explosions in the underground mine and deep holes.
