Claims24
A detonator-sensitive booster charge for use in blasting engineering comprising a mixture including a nitromethane and a cavity-forming means, wherein the cavity-forming means is configured as a hollow glass microsphere, and fumed silica, as well as a receptacle for an ignition device, wherein the booster charge is configured so as to be waterproof and temperature-resistant and comprises a concave curvature arranged on an opposite side of the receptacle for the ignition device.
A detonator-sensitive booster charge for use in blasting engineering comprising;
- a mixture and a receptacle for an ignition device, wherein
- the mixture comprises 85%-98.3% by weight nitromethane, 1.5%-10% by weight fumed silica, and 0.2%-10% by weight a cavity-forming means wherein the cavity-forming means comprises hollow glass microspheres, and
- the booster charge is configured so as to be waterproof and temperature-resistant.
A detonator-sensitive booster charge for use in blasting engineering comprising;
- a mixture and a receptacle for an ignition device, wherein the mixture comprises 92.5% by weight nitromethane, 6.5% by weight fumed silica, and 1% by weight a cavity-forming means wherein the cavity-forming means comprises hollow glass microspheres having a grain size of substantially 100 μm, and the booster charge is configured so as to be waterproof and temperature-resistant and comprises a concave curvature arranged on an opposite side of the receptacle from the ignition device.
