MAIN STAGES
Mass blast design
A team of drill & blast engineers develops a digital model of the block to be blasted based on the surveying data and telemetry data from drill rigs, as well as the results of previous blasts.
Based on the model and customer’s requirements, a required amount of explosives and a charge design are calculated, a suitable type of explosives in terms of density, velocity of detonation and efficiency is selected.
The parameters of the shotpile, particle size distribution, seismic effects and air blast are assessed.
The mass blast design includes a set of supporting documentation and permits required for handling commercial explosives.
Charging
Explosive charging, borethole tamping and installation of the explosive circuit are carried out according to the safety instructions and the mass blast schedule.
Explosives manufacturing and charging is performed by mobile explosive manufacturing units and controlled by the automated charging control system.
Modern components for electronic initiation systems and special devices for increasing the efficiency of explosives are used during hole stemming: universal charging sleeves, universal locking devices, compensators.
The entire process is subject to 24-hour security and enhanced safety measures.
Drilling
The fleet includes 43 high-performance drill rigs from the world’s leading manufacturer Epiroc (formerly Atlas Copco).
Drill rigs are fitted with special equipment and software for high-precision positioning, which allows to:
- Upload electronic data sheets and designs for drilling operations;
- Determine the position of the future borehole within 10 cm;
- Control the drilling process with the use of telemetry and transmit strength characteristics of the block to be drilled online to blast designers;
Blasting
Control of the shotpile and the quality of the blasted rock mass are ensured. KRU-Vzryvprom uses electronic initiation systems for:
Each blast is accompanied by monitoring of the environmental impact, dust and hazardous gas content in the atmosphere.
After the blast, engineers evaluate the fragmentation of the blasted rock mass to control the quality and adjust further designs.
- Controlling the shotpile of the blasted rock mass;
- Ensuring the quality of the blasted rock mass at minimal cost;
- Minimizing the seismic effect of the blast and the impact of the air blast.
- Monitor drilling quality: depth, spacing, quantity, and verify rock data.
