LAGRAN Company is proud to introduce ROCKKNIF, new unexplosive technology of block stone quarrying and rock breaking, which is assigned to Class 5.1 ADR.
Deflagration speed at combustion of mixture in boreholes, that makes 290 – 340 m/sec, assuredly provides absence of block damage, minimization of such harmful phenomena, as seismic vibrations, shock air wave, wreckage throwing and large noise.

The system is developed for blasters, contractors, quarry and mining managers.
A new gas-generating mixture and modular design the product range is currently the safest and efficient technology of block stone quarrying and rock breaking based rock breaking on the global market.

The ROCKKNIF technology
ROCKKNIF cartridges of new unexplosive technology are offered in the pre-assembled kind with the mounted system of initiation.
The ROCKKNIF technology
The ROCKKNIF technology is a completely new and unique solution and is specially designed for optimal block stone quarrying and rock breaking in difficult limited conditions.
An unique technological decision is the use of wares as pressure generators in boreholes and use of well-educated pressure for the cracking-off of blocks without stone damage.
Technical comparison, explosives vs ROCKKNIF
| Characteristic | Commercial explosives | Deflagrating ROCKKNIF |
| Reaction speed – confined | 3000 – 7000 m/sec | 450 m/sec |
| Reacion speed – unconfined | 3000 – 6000 m/s | 2 – 3 m/sec |
| Pressure | 1200 GPa | 720 -810 MPa |
| Sequential blasting | electronic, electric or shock tube | electric |
| Cost comparison | On par with conventional explosives (usage of blek powder rok , detonating cords, detonators, booster and emulsion, ANFO or NG base) | |
| Safety | High risk for secondary breakage and side wall damage | No crush zone or secondary damage to hanging wall or side wall |
