Technical services in drilling and blasting encompass expertise in optimizing the process for efficient rock excavation, including blast design, fragmentation assessment, and safety management, often involving specialized software and equipment.

Here’s a more detailed breakdown of technical services related to drilling and blasting:

1. Blast Design and Optimization:

• Rock Characterization:
  Understanding the type, strength, and behavior of the rock formation is crucial for effective blast design.
• Blast Pattern Design:
  Optimizing the spacing, depth, and angle of drill holes to achieve the desired fragmentation and minimize overbreak and backbreak.
• Explosive Selection:
  Choosing the appropriate type and quantity of explosives for the specific rock type and blasting conditions.
• Blast Simulation:
  Using software to model the blast process and predict the outcome, allowing for adjustments to the design before the actual blast.
• Mine to Mill Optimization:
  Optimizing the entire process from drilling and blasting to loading and hauling to maximize efficiency and productivity.

 

2. Fragmentation Assessment:

• Analyzing the size and distribution of broken rock after a blast: This helps determine if the blast design was successful and if any adjustments are needed for future blasts.
• Using specialized tools and techniques to measure fragmentation: This can include visual assessment, manual measurement, and the use of cameras and drones.

3. Safety Management:

Developing and implementing safety protocols for drilling and blasting operations:
This includes procedures for handling explosives, detonators, and other equipment, as well as for controlling vibrations and dust.
Monitoring and controlling vibrations:

• Using sensors to measure vibrations and ensure that they are within acceptable limits.
• Providing training to personnel involved in drilling and blasting operations: This ensures that they are aware of the risks and have the skills to work safely.

4. Specialized Equipment and Software:

Blast Modeling Software: Software that simulates the blast process and allows for optimization of blast design.

• Digital Detonators: Using digital detonators for more precise and controlled blasting.
• GPS-guided Drilling: Using GPS technology to ensure accurate drilling and placement of holes.
• Remote Drilling Operations: Using tele-remote operation to move operators off-site for increased safety and productivity.
• Drill Automation: Automating drilling cycles, navigation, bit changing, and pipe handling to reduce variability and improve efficiency.
