SEL-MIT is the trade name of an emulsion explosive mixture based on ammonium nitrate and mineral oil.
-
SEL-MIT is used as a main explosive in mining and quarrying in quarries and in field development works.
-
The SEL-MIT is manufactured in the factory and shipped in designated containers to work sites. With the help of a pump and a flexible feed tube, the SEL-MIT is transferred, in measured quantities and according to the customer’s request, from the containers directly into the drilled hole.
-
The SEL-MIT is not sensitive to operation by detonator. For activation, SEL-MEX cartridges should be used as a primer.
-
Loading vertical drills is easily done thanks to good flow properties, feed pressure through the pump and the feed tube.
​
Use of SEL-MIT
SEL-MIT serves as a main explosive in mining and quarrying works in quarries of stone and chalk, in construction of roads, in area development works and in any kind of large blasting operations when dealing with the need for a main explosive material with high water resistance, high speed detonation and the possibility of transporting the material to the drillings a few dozen meters from the location of the tanker.
Special use is made of the material to destroy special military munitions such as lighting, smoke and detonators/fuses that cannot be destroyed in any other way, but only by dismantling them.​
​
Operation
-
The SEL-MIT is activated by a primer.
-
SEL-MEX cartridges are the most suitable primer.
-
A detonating cord is not to be used when working with SEL-MIT.

Benefits
General
SEL-MIT is an explosive, which release during the explosion high energy thanks to the high explosion speed and density. Therefore, the SEL-MIT user is given the opportunity to space out the distances between the lines and the drills, to save explosives and drilling costs.
​Quality and efficiency
Emulsion explosives of SEL-MIT type can be applied with a pump, fed to the bottom of the drilled hole filling the volume of the hole with good contact on the sides.
All these qualities ensure maximum energy per meter.
The explosion results will be best with good crushing and removal of rock.
Safety
SEL-MIT is an explosive with low operating sensitivity, safer during work. The Activation requires a SEL-MEX primer.
Adaptation to work
SEL-MIT is suitable for all quarrying and quarrying works and works in places where the drilling diameter, surface conditions, the rock, and moister conditions require higher quality explosives with the possibility of distant feeding.
Health
SEL-MIT does not contain nitroglycerin and does not cause headaches. The oxygen balance of SEL-MIT is good and therefore there is no danger of toxin gases as a result of the explosion.
